If an online seller in the Philippines failed to deliver your order, sent the wrong or defective item, refused a refund, or disappeared after payment, a complaint with the Department of Trade and Industry (DTI) may be the fastest practical remedy. DTI complaints are meant to help consumers resolve disputes with businesses through mediation and, if needed, formal adjudication. This guide explains when DTI is the right office, what laws protect you, what evidence to prepare, how to file through the DTI Consumer CARe System or by email, and what to expect after filing.

When a DTI Complaint Against an Online Seller Is the Right Remedy

A DTI complaint is usually appropriate when your problem involves a business-to-consumer transaction with an online seller, e-commerce store, e-retailer, or online marketplace.

Common examples include:

You paid for an item but the seller did not deliver it.
The item delivered is fake, defective, damaged, incomplete, or different from the listing.
The seller advertised one product but sent another.
The seller refuses to honor a warranty.
The seller says “no refund” or “no return, no exchange” even though the product is defective or not as described.
The online listing, livestream, chat, or advertisement used misleading claims.
The seller or platform refuses to act on a valid complaint.

Under the Internet Transactions Act of 2023, or Republic Act No. 11967, Philippine rules on online transactions apply to business-to-business and business-to-consumer internet transactions within DTI’s mandate where at least one party is in the Philippines, or where the online merchant or platform is considered to be availing itself of the Philippine market. The law expressly excludes purely consumer-to-consumer transactions, such as a one-time private sale between two individuals, although DTI may still refer you to the proper office under the government’s “no wrong door” approach. (Supreme Court E-Library)

In practical terms, DTI is strongest when the seller is acting like a business: maintaining an online shop, repeatedly selling products, using a business name, advertising to the public, selling through an e-commerce platform, or accepting regular customer orders.

Your Legal Rights as an Online Buyer in the Philippines

Philippine law gives consumers several important protections when buying online. These rights do not disappear just because the transaction happened through Facebook, Instagram, TikTok, Shopee, Lazada, a website, chat, or livestream.

The Consumer Act protects buyers from deceptive and unfair sales practices

The main consumer protection law is the Consumer Act of the Philippines, or Republic Act No. 7394. It declares a State policy to protect consumers, promote their welfare, and establish standards of conduct for business and industry. (Supreme Court E-Library)

The Consumer Act prohibits deceptive sales acts or practices. These include false claims that a product has characteristics, benefits, quality, grade, style, or model that it does not actually have. It also covers misleading representations that an item is new, original, or unused when it is actually deteriorated, altered, reconditioned, second-hand, or different from what was represented. (Supreme Court E-Library)

The law also prohibits unfair or unconscionable sales acts or practices, especially when the seller takes advantage of a consumer’s lack of knowledge, urgency, vulnerability, or unequal bargaining position, or when the transaction is grossly one-sided. (Supreme Court E-Library)

Buyers may ask for repair, replacement, refund, or other appropriate remedies

For product or service imperfections, the Consumer Act makes suppliers jointly liable and allows consumers, in appropriate cases, to demand correction of the defect, replacement, reimbursement or refund, or price reduction. The law also recognizes timelines for correcting imperfections, subject to the circumstances and any valid agreement between the parties. (Supreme Court E-Library)

The DTI also recognizes that “No Return, No Exchange” notices cannot defeat a consumer’s legal remedies when the product is defective, imperfect, or not as represented. However, this does not mean a buyer has an automatic right to return a perfectly good item simply because they changed their mind. (Fair Trade Enforcement Bureau)

Online sellers have specific obligations under the Internet Transactions Act

The implementing rules of the Internet Transactions Act require online merchants to comply with Philippine laws, disclose prices properly, and ensure that goods match the condition, type, quantity, and quality described in the listing, sample, picture, or model. Goods should also be fit for their intended purpose and delivered with the accessories, manuals, packaging, and other inclusions advertised.

For online transactions involving defects, malfunction, loss, or failure to conform to warranty, the rules recognize consumer remedies such as repair, replacement, refund, and other remedies under the Consumer Act. The online merchant may be entitled to the return of the goods, but the return should be at no cost to the consumer when the complaint is valid.

Platforms may become liable in certain situations

Online marketplaces and e-retailers are not automatically liable for every seller’s wrongdoing, but the Internet Transactions Act and its rules create situations where a platform may face subsidiary or solidary liability. Examples include failure to exercise ordinary diligence, failure to remove prohibited or infringing goods after notice, failure to provide required seller contact details when the merchant has no Philippine legal presence, or failure to remove unsafe, dangerous, or prohibited goods after notice.

This matters when the seller is unreachable, uses a fake name, or has no clear Philippine address. Your DTI complaint should identify not only the seller but also the platform, store page, listing URL, order number, and any support ticket you already filed.

Before Filing: What to Do First

Before you file a DTI complaint against an online seller, take a few practical steps. These can make your complaint clearer, faster to process, and harder for the seller to deny.

1. Save your evidence immediately

Online sellers can delete listings, unsend messages, change product descriptions, or block you. Save evidence as early as possible.

Keep copies of:

Product listing, advertisement, livestream screenshot, or sales post
Seller profile, shop name, username, business name, phone number, email, and address if available
Order confirmation, invoice, receipt, or checkout page
Proof of payment, such as GCash, Maya, bank transfer, credit card, COD receipt, or platform payment record
Chat messages with the seller
Delivery tracking page, waybill, courier proof, or delivery receipt
Photos or videos of the item received
Unboxing video, if available
Warranty card, product manual, serial number, or authenticity certificate
Your written request for refund, replacement, repair, or delivery
Seller’s refusal, silence, blocking, or broken promises

Screenshots should show the date, time, username, page URL, and transaction details where possible.

2. Use the platform’s internal complaint process if there is one

If the purchase was made through an e-marketplace or e-retailer, use the platform’s return, refund, dispute, or customer service process first. The rules under the Internet Transactions Act say an aggrieved party should avail of the internal redress mechanism of the platform or e-retailer before going to government, court, or alternative dispute resolution. This internal process is deemed exhausted if the complaint remains unresolved after seven calendar days from filing.

Save the ticket number, email confirmation, chat transcript, and platform decision.

3. Send a clear written demand to the seller

A written demand is not always enough to solve the issue, but it helps show that you tried to resolve the matter in good faith.

Your message should be direct and factual:

Identify the item, order number, payment date, and amount.
State what went wrong.
Attach or mention proof.
Ask for a specific remedy: refund, replacement, repair, delivery, or cancellation.
Give a reasonable deadline.

Avoid threats, insults, or long emotional messages. DTI mediation is easier when your records are organized and professional.

4. Check if DTI is the only office you need

Some online seller problems involve more than one agency. DTI may receive or refer complaints under a “no wrong door” system, but filing with the most relevant office can save time. RA 11967 authorizes the E-Commerce Bureau to receive and refer business and consumer complaints involving internet transactions. (Supreme Court E-Library)

Problem	Possible office or remedy
Defective, wrong, misleading, or undelivered consumer product from an online seller	DTI
Unauthorized bank, credit card, or e-wallet transaction	Bank, e-wallet provider, BSP consumer assistance channels
Online scam, fake identity, phishing, or deliberate fraud	PNP Anti-Cybercrime Group, NBI Cybercrime Division, prosecutor’s office
Food, medicine, cosmetics, health products, or medical devices	FDA, and possibly DTI depending on the sales practice
Telco, internet, SIM, or device/network-related issue	NTC, and possibly DTI for sales practices
Claim for damages beyond refund, repair, or replacement	Regular court or small claims court, depending on the case

Documents and Information to Prepare

The DTI complaint form asks for information about the complainant, respondent, product or service, proof of transaction, narration of facts, and requested settlement. The form includes proof such as official receipt, warranty card, deposit slip, delivery receipt, sales invoice, and other transaction records. It also allows remedies such as replacement, repair, refund, or other settlement terms. (Fair Trade Enforcement Bureau)

Requirement	What to prepare	Practical tip
Your personal details	Full name, address, email, phone number, valid government ID	Use an email you check often because notices may be sent there.
Seller details	Business name, shop name, username, profile link, address, phone, email, website, social media page	If the seller has no address, provide every identifier you have.
Transaction details	Date of order, item name, quantity, amount paid, payment method, order number	Be precise. “Paid ₱3,499 by GCash on May 5, 2026” is better than “I paid last month.”
Proof of payment	Receipt, transfer slip, platform payment record, COD receipt, bank or e-wallet reference number	Hide unrelated account balances, but keep the transaction reference visible.
Proof of seller’s promise	Listing, ad, screenshots, chat, livestream screenshots, product description	Show what the seller represented before you bought.
Proof of defect or non-delivery	Photos, videos, tracking record, courier report, repair diagnosis	For defective items, take clear photos or videos under good lighting.
Prior complaint record	Platform ticket, seller demand letter, customer service response	This is important if the marketplace process was already used.
Requested remedy	Refund, repair, replacement, delivery, cancellation, or other specific request	DTI mediation works best when your demand is specific and realistic.

For overseas Filipinos or foreigners, the main requirement is still evidence of the transaction. If you authorize someone in the Philippines to attend or coordinate for you, prepare a signed authorization letter or special power of attorney if requested by the receiving office. If the document is executed abroad, ask the relevant office whether notarization, consular acknowledgment, or apostille authentication is required for your specific use.

How to File a DTI Complaint Against an Online Seller

1. File through the DTI Consumer CARe System or other official channels

For online filing, DTI directs consumers to the DTI Consumer CARe System. The system allows consumers to submit complaints and track resolution. Registration generally requires your name, address, email, password, phone number, and valid government ID details. (Philippine Information Agency)

DTI’s FTEB guidance also states that Metro Manila complainants may submit complaints through the online portal, email a duly accomplished complaint form or complaint letter, or file in person. Complaints may be emailed to DTI ConsumerCare, while FTEB is located at the Trade and Industry Building in Makati. (Fair Trade Enforcement Bureau)

If you are outside Metro Manila, you may file with the appropriate DTI regional or provincial office. DTI regional guidance requires the complaint to include the complainant’s and respondent’s contact details, a narration of facts, the demand, proof of transaction, and a government ID. (E-Sigaw)

2. Identify the correct respondent

Name the seller as clearly as possible. If the seller used a shop name, page name, or username, include that. If the transaction happened through a marketplace, include the platform and order number.

Use all available identifiers:

Registered business name, if shown
Online shop name
Seller username or handle
Marketplace store URL
Facebook, Instagram, TikTok, or website link
Seller’s phone number or email
GCash, Maya, bank account, or payment name used
Courier sender details
Return address on the waybill
Screenshots of the seller profile and listing

If you do not know the seller’s real name, do not leave the complaint vague. Write the shop name and all available identifying details.

3. Write a clear narration of facts

Your narration should be chronological and specific. DTI officers handle many complaints, so make it easy to understand the issue quickly.

A useful format is:

Date you saw the listing or offer
What the seller represented
Date and amount of payment
Delivery or non-delivery details
What was wrong with the item or transaction
When you contacted the seller
How the seller responded
What remedy you are requesting

Example:

On May 5, 2026, I ordered one “brand-new original” wireless earbud set from ABC Online Shop through its Facebook page for ₱3,499. I paid the same day through GCash to the account shown in the seller’s chat message. The seller promised delivery within five days. On May 12, 2026, I received an item that was not the model advertised and did not turn on. I immediately sent photos and a video to the seller and requested a refund or replacement. The seller refused and said all sales were final. I am requesting a full refund or replacement with the exact item advertised.

4. State the remedy you want

Be specific. Do not simply write “I want justice.” For most DTI consumer complaints, the practical remedies are:

Refund
Replacement
Repair
Completion of delivery
Cancellation of transaction
Correction of misleading practice
Removal of prohibited, unsafe, or deceptive listing where appropriate

DTI adjudication can grant remedies such as repair, replacement, or refund, but it is not the usual forum for moral damages, inconvenience damages, lost income, litigation expenses, or similar money claims beyond the purchase-related remedy. DTI’s own adjudication guidance states that damages and other expenses are generally for the regular courts, while DTI remedies are limited to repair, replacement, or refund of the purchase price. (Fair Trade Enforcement Bureau)

5. Attach your evidence

Upload or submit your evidence in an organized way. Use descriptive file names if possible:

Proof-of-payment-GCash-May-5-2026.png
Seller-chat-refusing-refund.pdf
Product-listing-screenshot.pdf
Defective-item-video.mp4
Courier-waybill.jpg
Platform-ticket-decision.pdf

If the portal limits file size, combine screenshots into a PDF or submit the most important evidence first. Keep the originals.

6. Monitor your email, phone, and portal account

After filing, watch for DTI notices. If you miss a mediation schedule or fail to submit required documents, the complaint may be delayed or dismissed. Respond promptly and keep your tone factual.

What Happens After You File

DTI consumer complaints generally pass through mediation first. Mediation is a settlement process where a neutral DTI officer helps the consumer and seller try to reach a voluntary resolution. DTI’s mediation process is based on Article 159 of the Consumer Act, Department Administrative Order No. 20-02, and Executive Order No. 913. (Fair Trade Enforcement Bureau)

If mediation fails, the case may proceed to formal adjudication. DTI guidance states that mediation is mandatory and is a condition precedent before a formal complaint may be filed with the Adjudication Division. A Certificate to File Action may be issued after failed mediation. (Fair Trade Enforcement Bureau)

Stage	What happens	Practical reality
Initial review	DTI checks the complaint, documents, and jurisdiction	Incomplete seller details or missing proof can slow this down.
Referral or routing	DTI may route the complaint to the proper regional office, FTEB, or another agency	This is common when the issue involves payment providers, regulated products, or another government office.
Mediation	DTI helps both sides settle	Many cases end here if the seller agrees to refund, replace, repair, or complete delivery.
Certificate to File Action	Issued if mediation fails	This allows the consumer to pursue formal adjudication before DTI.
Formal adjudication	The complaint is heard more formally by an adjudication officer	You may need a verified complaint, evidence, sworn statements, and certification against forum shopping.
Decision	DTI issues a decision after the case is submitted for decision	DTI guidance states decisions are issued within 15 working days from submission or deemed submission for decision.
Execution	If the losing party does not comply, the winning party may seek execution	DTI may issue an order or writ of execution through its process.

A lawyer is not mandatory in DTI adjudication, although a party may be represented by counsel. DTI also states that no filing fee is charged if the formal complaint is sufficient and complete. (Fair Trade Enforcement Bureau)

Timelines, Fees, and Deadlines

Item	Usual rule or practical guide
Platform internal redress	If unresolved after seven calendar days, the internal mechanism is deemed exhausted under the Internet Transactions Act rules.
DTI filing fee	DTI guidance states there is no filing fee for a sufficient and complete formal complaint.
Mediation timeline	Varies depending on routing, notice to seller, completeness of documents, and seller cooperation.
Formal DTI decision	DTI guidance states the decision is issued within 15 working days from submission or deemed submission for decision.
Appeal period under the Consumer Act	The Consumer Act provides an appeal to the Department Secretary within 15 days from receipt of the order.
Prescriptive period	Consumer Act actions or claims generally prescribe within two years from the consumer transaction or deceptive/unfair act, and hidden defects are counted from discovery.

The safest approach is to file as soon as you have confirmed that the seller or platform will not resolve the matter. Waiting too long makes evidence harder to preserve and may create prescription issues. (Supreme Court E-Library)

Common Problems When Complaining Against Online Sellers

The seller says “no refund” or “all sales final”

A seller cannot use a “no refund” or “no return, no exchange” policy to avoid responsibility for a defective, wrong, fake, incomplete, or misrepresented product. Philippine consumer law recognizes remedies such as repair, replacement, and refund for valid complaints. But if the product is not defective and you simply changed your mind, the seller is not automatically required to accept a return. (Fair Trade Enforcement Bureau)

The seller blocked you

Being blocked does not prevent you from filing. Screenshot the blocked profile, the chat history, the payment record, and the seller’s page or listing if still available. Include payment details and courier information because these may help identify the seller.

The seller deleted the listing

Deleted listings are common in online complaints. This is why early screenshots matter. If you still have the order confirmation, chat, platform notification, email receipt, or payment reference, attach those. If the listing appears in your browser history or marketplace order history, save it immediately.

The seller is on Facebook, Instagram, or TikTok

DTI complaints can still be filed if the seller is acting as an online merchant. The challenge is identification. Social media sellers often use aliases, so include the page URL, profile link, screenshots, payment account, phone number, delivery details, and any public posts showing regular selling activity.

The seller is on Shopee, Lazada, TikTok Shop, or another marketplace

Use the platform’s return/refund process first and save the result. If unresolved after the internal process, include the platform ticket number and decision in your DTI complaint. If the seller has no clear Philippine contact information, explain that in your complaint because platform obligations may become relevant under the Internet Transactions Act rules.

The item was delivered but is not what you ordered

Focus your evidence on the difference between the listing and the item received. Attach the listing description, product photo, variant selected, invoice, waybill, and actual item photos. If the issue is technical, a short video showing the defect may help.

The seller is abroad

RA 11967 and its rules recognize that online merchants and platforms may still be covered when they avail themselves of the Philippine market or have minimum contacts with the Philippines. However, enforcement can be harder when the seller has no Philippine presence. Include the platform, payment channel, shipping records, and any Philippine-facing advertising or delivery details. (Supreme Court E-Library)

You want compensation for stress, lost time, or business loss

DTI is mainly useful for consumer remedies such as refund, repair, replacement, and compliance with consumer laws. If you want damages beyond the purchase price, you may need to consider court action. For money claims not exceeding ₱1,000,000 arising from contracts such as sale of personal property, small claims court may be relevant. (Supreme Court of the Philippines)

When the Problem May Be a Scam or Criminal Case

Not every bad online transaction is automatically a criminal case. A delayed shipment, defective item, or refund dispute is often a consumer complaint. But if the seller used a fake identity, fictitious transaction, false pretenses, or fraudulent scheme from the beginning, criminal fraud may be involved.

Under the Revised Penal Code, estafa may involve false pretenses or fraudulent acts committed before or at the same time as the fraud, including the use of a fictitious name, false qualifications, or imaginary transactions. (Lawphil)

If the facts show a deliberate online scam, you may consider reporting to:

PNP Anti-Cybercrime Group
NBI Cybercrime Division
The prosecutor’s office for possible criminal complaint
Your bank, e-wallet provider, or payment channel for possible transaction tracing or account action

You can still preserve and organize your DTI evidence because the same documents—payment proof, chat logs, seller identity, account numbers, delivery records—may also help in a criminal or payment-provider complaint.

How to Write a Strong DTI Complaint

A strong complaint is short, specific, and evidence-based. It should answer four questions:

What did the seller promise?
What did you pay and when?
What went wrong?
What remedy do you want?

Avoid exaggerations and legal conclusions you cannot prove. Instead of writing, “The seller is a scammer and should be jailed,” write:

I paid ₱8,500 on June 1, 2026 for a brand-new mobile phone advertised on the seller’s Facebook page. The seller confirmed receipt of payment and promised shipment within three days. No item was delivered. The seller stopped responding on June 5, 2026 and later blocked my account. I am requesting a full refund and appropriate DTI action based on the attached proof of payment, chat screenshots, and seller profile.

This style is easier for DTI to process and harder for the seller to dismiss.

Frequently Asked Questions

Can I file a DTI complaint online against a Shopee, Lazada, TikTok Shop, or Facebook seller?

Yes, if the seller is acting as an online merchant or business and the issue involves a consumer transaction within DTI’s mandate. For marketplace purchases, use the platform’s internal dispute process first and attach the result to your DTI complaint. For Facebook, Instagram, or TikTok sellers, include the seller’s profile link, screenshots, payment details, and proof that the seller was offering goods to the public.

Do I need an official receipt to file a DTI complaint?

An official receipt helps, but it is not the only possible proof. DTI complaint forms recognize other proof of transaction, such as warranty cards, deposit slips, delivery receipts, sales invoices, and similar records. For online purchases, payment confirmations, e-wallet receipts, bank transfer slips, marketplace order records, and chat confirmations can be important evidence. (Fair Trade Enforcement Bureau)

Is filing a DTI complaint free?

DTI guidance states that consumer complaints may be submitted free of charge, and formal complaints with complete and sufficient requirements do not require a filing fee. (Fair Trade Enforcement Bureau)

How long does a DTI complaint take?

It depends on the completeness of your documents, whether the seller can be contacted, whether the complaint must be routed to another office, and whether the seller cooperates in mediation. If the case reaches formal adjudication, DTI guidance states that a decision is issued within 15 working days from the time the case is submitted or deemed submitted for decision. (Fair Trade Enforcement Bureau)

Can DTI force an online seller to refund me?

DTI can help mediate a refund, replacement, repair, or other settlement. If mediation fails and the case proceeds to adjudication, DTI may issue orders within its authority. DTI guidance recognizes repair, replacement, or refund as formal remedies, but claims for damages and other expenses generally belong in the regular courts. (Fair Trade Enforcement Bureau)

Do I need a lawyer for a DTI complaint?

No. DTI guidance states that representation by a lawyer is not mandatory, although a party may choose to be represented by counsel. For many consumer complaints, organized documents and a clear narration are more important than legal jargon. (Fair Trade Enforcement Bureau)

What if the online seller has no DTI registration or business permit?

You can still file if you have enough information to identify the seller or transaction. Lack of visible registration may become part of the issue. Provide the shop name, username, profile link, payment account, courier details, phone number, and screenshots. DTI may also route or refer the matter if another agency is involved.

What if the seller is just an individual and not a business?

If it is a purely private, one-time consumer-to-consumer sale, the Internet Transactions Act excludes it from its coverage. DTI may still review the complaint or refer you to the proper office, but your practical remedies may include direct demand, small claims court, or a criminal complaint if there was fraud. (Supreme Court E-Library)

Can foreigners or OFWs file a DTI complaint?

Yes, if the transaction falls within DTI’s jurisdiction and involves the Philippine market or a party in the Philippines. Foreigners, OFWs, and Filipinos abroad should prepare clear proof of identity, transaction records, seller details, and authorization documents if someone in the Philippines will act for them.

What if DTI says my complaint belongs to another agency?

That can happen. Online transactions may involve payment systems, regulated products, telecommunications, courier issues, or criminal fraud. Under RA 11967, the E-Commerce Bureau may receive and refer complaints involving internet transactions under a “no wrong door” approach. (Supreme Court E-Library)

Key Takeaways

A DTI complaint is usually appropriate for online seller problems involving defective goods, wrong items, misleading ads, non-delivery, warranty refusal, or invalid “no refund” policies.
File through the DTI Consumer CARe System, by email, or through the appropriate DTI office, depending on your location and the nature of the complaint.
Use the platform’s internal dispute process first when buying through an e-marketplace; if unresolved after seven calendar days, the internal process is deemed exhausted under the Internet Transactions Act rules.
Strong evidence is crucial: save the listing, chats, proof of payment, delivery records, photos, videos, and seller profile information.
The most common DTI remedies are refund, repair, replacement, delivery, or settlement—not damages for stress, inconvenience, or lost income.
If the seller used fake identity, false pretenses, phishing, or a deliberate fraudulent scheme, consider reporting the matter to cybercrime authorities in addition to any consumer complaint.
Do not wait too long. Consumer claims under the Consumer Act generally have a two-year prescriptive period, and online evidence can disappear quickly.
