When an online seller takes your payment but does not deliver, sends a fake or defective item, refuses a refund, or ignores your messages, a DTI complaint can be a practical way to force the issue into a formal process. In the Philippines, consumer complaints against online sellers are usually handled first through mediation, and if mediation fails, the case may move to adjudication where the DTI can order remedies and impose administrative penalties. This guide explains when DTI is the right office, what evidence to prepare, how to file, what happens after filing, and what to do when the case involves a platform like Shopee, Lazada, TikTok Shop, Facebook Marketplace, Instagram, or a seller based abroad.

When a DTI Complaint Against an Online Seller Is Appropriate

A DTI complaint is usually appropriate when the dispute involves a consumer transaction with a business seller. This includes online stores, marketplace sellers, social media sellers acting as a business, direct website sellers, and e-retailers.

Common examples include:

You paid for an item, but the seller did not deliver.
The seller delivered a different item from what was advertised.
The product is defective, fake, expired, unsafe, or unusable.
The seller refuses to honor a warranty, return, refund, or replacement policy.
The seller used misleading product photos, fake discounts, or false claims.
The platform or marketplace failed to act after you filed a valid complaint through its internal system.

DTI’s own E-Commerce FAQ says complaints against online sellers may be sent to the DTI Fair Trade Enforcement Bureau, and it also says DTI accommodates complaints involving online and offline businesses. (DTI ECommerce)

However, not every online dispute is a DTI case. A purely private, one-time sale between two individuals may be treated as consumer-to-consumer or C2C. Republic Act No. 11967, or the Internet Transactions Act of 2023, expressly excludes C2C transactions from its coverage, while applying to business-to-business and business-to-consumer internet transactions within DTI’s mandate where one party is in the Philippines or the seller/platform is availing of the Philippine market. (Supreme Court E-Library)

That distinction matters in real life. If you bought from a registered online store, an active marketplace seller, or a seller who regularly sells for profit, DTI is usually the first practical route. If you sent money to a completely anonymous person who immediately disappeared, changed names, blocked you, and used fake identities, you may still report the consumer aspect to DTI, but you should also consider a criminal complaint with the PNP Anti-Cybercrime Group or NBI Cybercrime Division.

Legal Basis: Your Rights Against Online Sellers in the Philippines

Consumer Act of the Philippines: Deceptive Sales and Defective Products

The main consumer protection law is Republic Act No. 7394, or the Consumer Act of the Philippines. It prohibits deceptive, unfair, and unconscionable sales acts. In the Supreme Court case Autozentrum Alabang, Inc. v. Spouses Bernardo, the Court quoted Article 50 of the Consumer Act and explained that a seller commits a deceptive act when it represents a product as having a quality, standard, model, or condition that it does not actually have. The same decision discussed liability for defective products under Article 97 and DTI’s power to impose restitution, rescission, refund, and administrative fines. (Supreme Court E-Library)

This is why DTI complaints are especially useful for online purchases where the seller’s advertisement was misleading. For example:

A “brand new” item was actually used or refurbished.
A “100% authentic” product turned out to be counterfeit.
A seller advertised one model but delivered a cheaper model.
A product was promoted as safe, original, sealed, or complete, but was not.

The Supreme Court also recognized in Autozentrum that DTI has special knowledge and expertise in consumer matters, so its factual findings in matters within its jurisdiction are generally given respect when supported by evidence. (Supreme Court E-Library)

Internet Transactions Act of 2023: Online Seller and Platform Liability

The Internet Transactions Act modernized consumer protection for e-commerce. It gives DTI regulatory jurisdiction over the use of the internet for e-commerce by online merchants, e-retailers, e-marketplaces, digital platforms, and third-party platforms. (Supreme Court E-Library)

Under the 2024 Implementing Rules and Regulations, an online consumer may pursue repair, replacement, refund, or other remedies when there is a defect, malfunction, loss without the consumer’s fault, failure to conform with warranty, or liability arising from the online contract.

The IRR also provides an important rule for online complaints: before filing with a court or government agency, the aggrieved party should use the internal redress mechanism of the digital platform, e-marketplace, or e-retailer. This internal remedy is considered exhausted if the complaint remains unresolved after seven calendar days from filing.

This does not mean the platform can delay you forever. It means you should first file a ticket, refund request, return request, or complaint within the app or website, then keep proof that it remained unresolved after seven calendar days.

The IRR further states that the e-retailer or online merchant is primarily liable for indemnifying the online consumer in civil actions or administrative complaints arising from the internet transaction. An e-marketplace or digital platform may become subsidiarily liable in specific situations, such as failure to exercise ordinary diligence, failure to act after notice, or failure to provide contact details where the merchant has no legal presence in the Philippines.

A platform may also become solidarily liable with the online merchant or e-retailer if, after notice, it fails to expeditiously remove or disable access to goods or services that are prohibited by law, imminently injurious, unsafe, or dangerous.

Civil Code Remedies for Breach of Warranty

The Civil Code still matters because online sales are still sales contracts. The Internet Transactions Act IRR itself says that Civil Code provisions on sales, obligations, and contracts apply in construing the rights and responsibilities of the parties.

Under Article 1599 of the Civil Code, when there is a breach of warranty by the seller, the buyer may choose remedies such as keeping the goods and claiming damages, refusing acceptance and claiming damages, or rescinding the sale and recovering the price paid. (Lawphil)

In practical terms, your requested remedy should match the problem:

Problem	Usual remedy to request
No delivery after payment	Delivery, full refund, or cancellation with refund
Wrong item delivered	Replacement with correct item or full refund upon return
Defective item	Repair, replacement, refund, or warranty service
Fake item advertised as original	Refund, return without cost to consumer, and possible administrative action
Missing parts/accessories	Completion of delivery, price reduction, or replacement
Unsafe or prohibited item	Refund, reporting, and possible DTI enforcement action

Before Filing: Use the Seller or Platform Complaint System First

For online transactions, do not jump straight to a long emotional complaint without first creating a clear record. The seven-calendar-day internal redress rule under the Internet Transactions Act IRR makes this especially important.

Do these first:

Message the seller clearly. State the order number, item, date of payment, problem, and remedy you want.
Use the platform’s return/refund system. Do not rely only on chat if the app has a formal dispute button.
Save screenshots before anything disappears. Capture the product listing, seller profile, chat thread, order status, tracking page, and refund ticket.
Give a reasonable deadline. For online platform disputes, seven calendar days is the key period under the IRR.
Avoid threats, insults, or exaggerated claims. DTI mediation is easier when your records show that you acted reasonably.

A concise message is usually enough:

I am filing this formal request for refund/replacement regarding Order No. . I paid ₱ on ____. The item delivered was defective/different from the advertised item because ____. Attached are photos, screenshots, and proof of payment. Please resolve this within seven calendar days. If unresolved, I will file a consumer complaint with DTI and attach this request as proof that I exhausted the platform/seller redress process.

Step-by-Step Guide: How to File a DTI Complaint Against an Online Seller

1. Identify the Correct Respondent

List every party involved:

Seller’s shop name
Seller’s real name, if known
Business name, DTI business name, SEC name, or BIR details, if shown
Platform name
Seller’s address, email, phone number, and social media links
Order number, tracking number, and transaction reference number

For marketplace purchases, include both the seller and the platform in your narrative when the platform handled payment, delivery, refund decisions, or post-purchase support. This is important because the Internet Transactions Act recognizes possible liability of platforms in certain circumstances.

If the seller is foreign but sells to Philippine customers, do not automatically assume DTI has no jurisdiction. The Internet Transactions Act has extraterritorial application when the person engaged in e-commerce avails of the Philippine market and establishes minimum contacts, even without legal presence in the Philippines.

2. Prepare Your Evidence

DTI complaints are evidence-driven. Screenshots alone can help, but screenshots plus payment records and delivery records are much stronger.

Evidence	Why it matters
Order confirmation	Proves what you bought and when
Receipt, invoice, or payment confirmation	Proves payment and amount
Product listing screenshots	Proves seller’s representations
Chat logs	Proves promises, admissions, refusal, or delay
Platform ticket history	Proves you used internal redress first
Delivery tracking	Proves non-delivery, wrong delivery, or delay
Photos/videos of item	Proves defect, damage, missing parts, or wrong item
Warranty card/manual	Supports warranty claim
Seller profile and business details	Helps DTI identify and notify respondent
Valid ID	Confirms complainant identity
Authorization letter or SPA	Needed if another person files or appears for you

For high-value products, unboxing videos, courier waybills, repair reports, and service center findings can be very useful. For electronics, appliances, gadgets, and luxury items, try to obtain a written assessment from an authorized service center when the defect is disputed.

3. Use the Proper DTI Filing Channel

For complaints involving online sellers, DTI’s E-Commerce FAQ says complaints may be sent to the DTI Fair Trade Enforcement Bureau at fteb@dti.gov.ph, with eco@dti.gov.ph copied. (DTI ECommerce)

DTI-FTEB’s official FAQ also says complainants within Metro Manila may submit complaints through the online portal consumercare.dti.gov.ph, or by sending a duly accomplished complaint form or complaint letter to consumercare@dti.gov.ph, or in person to the FTEB Director at the DTI Fair Trade Enforcement Bureau, 5th Floor, Trade and Industry Building, 361 Sen. Gil J. Puyat Avenue, Makati City. (Fair Trade Enforcement Bureau)

DTI-FTEB’s contact page lists its email as fteb@dti.gov.ph and its office at the Trade and Industry Building, 361 Sen. Gil Puyat Avenue, Makati City. (Fair Trade Enforcement Bureau)

DTI also has an online dispute resolution framework. The Internet Transactions Act IRR provides for an Online Dispute Resolution System as a platform to facilitate alternative dispute resolution for online consumers, online merchants, e-retailers, e-marketplaces, and digital platforms.

In practice, use the most available channel:

Situation	Practical filing route
You are in Metro Manila	DTI Consumer CARe portal, `consumercare@dti.gov.ph`, or FTEB in Makati
You are outside Metro Manila	Nearest DTI regional/provincial office or online/email channel
Seller is an online platform seller	Email FTEB and copy E-Commerce Bureau; attach platform ticket
Seller is a social media business seller	Email FTEB with screenshots of profile, posts, chats, payment
You are an OFW or foreigner abroad	File by email/online if accepted; authorize a Philippine representative if appearance or signing is required

4. Write a Clear Complaint Narrative

Your complaint should be factual and organized. DTI officers handle many cases; a clean timeline helps them evaluate faster.

Include:

Your name, address, email, and mobile number.
Seller’s name, shop name, platform, address, email, mobile number, and links.
Date of order and payment.
Item description and price.
What the seller promised.
What actually happened.
What you did to resolve it with the seller/platform.
The remedy you are asking for.
List of attachments.

A strong complaint does not need dramatic language. It needs dates, proof, and a specific remedy.

Example of a clear relief clause:

I respectfully request that the respondent be directed to refund the purchase price of ₱____, including delivery fee, because the item delivered was materially different from the product advertised. In the alternative, I request replacement with the correct item at no additional cost to me, including return shipping.

5. Submit the Complaint Form or Complaint Letter

DTI-FTEB has an Initial Complaint Form listed on its downloadable forms page. (Fair Trade Enforcement Bureau)

If you cannot access the form, a complaint letter can still be prepared with the required information and attachments. Keep one PDF file for the complaint narrative and separate clearly named files for evidence, such as:

01_Order_Confirmation.pdf
02_Proof_of_Payment.pdf
03_Product_Listing_Screenshots.pdf
04_Chat_with_Seller.pdf
05_Platform_Refund_Ticket.pdf
06_Photos_of_Defect.pdf

This makes the case easier to review and reduces the risk that important proof will be missed.

6. Attend Mediation

Mediation is the first key stage. It is a meeting, often online or by phone depending on the office and system used, where a DTI officer helps both sides reach a settlement.

DTI-FTEB’s Mediation Division conducts mediation under Article 159 of the Consumer Act and related rules, including DAO No. 20-02, Series of 2020. (Fair Trade Enforcement Bureau)

Mediation is mandatory. DAO No. 13-02 states that a complaint cannot be submitted for arbitration without passing through mediation first. It also provides that if mediation succeeds, a mediation agreement is prepared and becomes final and executory; if no settlement is reached or the respondent fails or refuses to participate, the mediation officer issues a notice of failure and submits the case for adjudication. (Supreme Court E-Library)

At mediation, be ready to answer:

What exact amount did you pay?
What specific product or service was promised?
What exactly was wrong?
What remedy do you want?
Are you willing to return the item if refunded?
Did the seller offer repair, replacement, partial refund, or vouchers?
Why is that offer acceptable or unacceptable?

7. If Mediation Fails, Prepare for Adjudication

Adjudication is more formal. DTI’s Adjudication Division resolves consumer complaints for violations of RA 7394 pursuant to Article 159 and handles formal charges for violations of trade and industry laws. (Fair Trade Enforcement Bureau)

At this stage, DTI may require a more formal complaint, sworn statements, evidence, and certifications. The case may be decided based on documents, position papers, and hearings.

Possible outcomes include:

Refund
Replacement
Repair
Compliance with warranty
Restitution or rescission
Cease and desist order
Administrative fines
Other lawful orders depending on the violation

Under the Internet Transactions Act IRR, DTI may impose administrative penalties for online deceptive, unfair, or unconscionable sales acts, in addition to penalties under the Consumer Act. The IRR states that the consumer may claim damages in court or seek administrative penalties by filing with DTI within two years from the time the cause of action arose.

Practical Timelines, Fees, and Costs

Item	What to expect
Internal platform/seller redress	Deemed exhausted if unresolved after 7 calendar days under the ITA IRR
DTI acknowledgment	Varies by office, portal status, and completeness of documents
Mediation	Often scheduled within days or weeks, but may take longer depending on volume and respondent availability
Adjudication	Can take several months if evidence is disputed or parties file many submissions
DTI filing fee	Generally treated as accessible consumer redress; confirm with the handling DTI office for any required documentary or certification costs
Lawyer	Usually not required for mediation, but may help for high-value or complex adjudication
Other costs	Printing, scanning, notarization if required, courier, transportation, and possible representative documents

For many ordinary e-commerce complaints, the biggest bottleneck is not the law but the evidence. Missing proof of payment, deleted listings, unrecorded phone calls, and unclear seller identity can delay or weaken a complaint.

Common Pitfalls That Can Hurt Your DTI Complaint

Filing Without Proof of Purchase

A screenshot of a product is not enough. DTI needs to see that you actually bought from the seller. Keep receipts, invoices, payment confirmations, order numbers, bank transfer slips, GCash/Maya records, card statements, and delivery records.

Waiting Too Long

The Internet Transactions Act IRR refers to filing with DTI for administrative penalties within two years from the time the cause of action arose.

Do not wait months before saving evidence. Online listings, seller profiles, and chat accounts can disappear quickly.

Asking for an Unrealistic Remedy

A refund may require return of the item. The ITA IRR states that when the online consumer avails of replacement or refund, the online merchant or e-retailer is entitled to the return of the original goods delivered, without cost to the online consumer, within a reasonable period unless otherwise agreed.

If you want a refund, be prepared to return the item unless it was never delivered, is unsafe to ship, or the parties agree otherwise.

Treating Buyer’s Remorse as a Legal Violation

Not every change of mind is a DTI complaint. The ITA IRR’s online consumer code says consumers must exercise ordinary diligence and should not make false, fraudulent, or unsubstantiated claims. It also limits cancellation of confirmed orders in certain situations, such as paid orders already in transit, perishable goods, food prepared by quick service restaurants, or made-to-order goods where materials have already been purchased or prepared, unless exceptions apply.

Ignoring the Platform’s Complaint System

If the sale happened through a platform, use the platform system first. This helps satisfy the internal redress requirement and creates a record showing whether the platform acted properly.

Filing Only Against the Platform When the Seller Is Identifiable

In many cases, the online merchant is primarily liable. The platform’s liability may depend on its own failure, notice, lack of diligence, or inability to provide seller contact details.

Name both when appropriate, but explain each party’s role.

What If the Seller Is a Scammer?

A DTI complaint is for consumer redress and administrative action. If there is clear fraud, such as fake identity, fake tracking, repeated non-delivery schemes, use of mule accounts, or immediate blocking after payment, criminal remedies may also apply.

Possible criminal angles include:

Estafa under Article 315 of the Revised Penal Code, if deceit caused you to part with money.
Cybercrime-related liability under RA 10175 if the crime was committed through information and communications technology. The Cybercrime Prevention Act IRR states that crimes under the Revised Penal Code and special criminal laws committed through ICT are covered by the Act, with the penalty generally one degree higher. (Supreme Court E-Library)
Computer-related fraud or identity theft if the case involves unauthorized computer data, fake accounts, or stolen identity information. (Supreme Court E-Library)

For scam cases, preserve digital evidence immediately. Do not delete chats. Save the seller’s profile URL, account number, payment recipient name, mobile number, email address, courier details, and all screenshots with dates visible.

Can Foreigners or OFWs File a DTI Complaint?

Yes, if the transaction has a Philippine connection and falls within DTI’s consumer protection mandate. The Internet Transactions Act covers covered internet transactions where one party is situated in the Philippines or where the seller/platform is availing of the Philippine market and has minimum contacts in the Philippines. (Supreme Court E-Library)

For foreigners in the Philippines, the process is generally the same: prepare ID, proof of transaction, evidence, and complaint narrative.

For OFWs or complainants abroad:

File through online or email channels when available.
Use scanned evidence.
Make sure your email and phone number are active.
If a representative will attend mediation or sign documents for you, DTI may require written authorization or a Special Power of Attorney.
If the SPA is executed abroad, practical processing may require notarization before a Philippine consulate or apostille, depending on where it is executed and how the receiving office treats the document.

When Small Claims Court May Be Better Than DTI

DTI is often best when you want mediation, refund, replacement, repair, or administrative action against a business. But if your main goal is simply to collect a definite amount of money, and the seller is identifiable, small claims court may be another route.

The Supreme Court’s rules on expedited procedures increased the threshold for small claims cases to ₱1,000,000, without distinction between Metro Manila and other areas, and cover money claims arising from sales of personal property, among others. (Supreme Court of the Philippines)

Small claims may be useful when:

The seller is identifiable and has an address.
The amount is clear.
You want a money judgment.
DTI mediation failed.
The matter is more contractual than regulatory.

DTI and small claims are different remedies. DTI focuses on consumer protection and administrative enforcement. Small claims court focuses on collecting or recovering money.

Frequently Asked Questions

How do I file a DTI complaint against an online seller?

Prepare your complaint narrative, proof of purchase, screenshots, payment records, seller details, and proof that you tried to resolve the issue through the seller or platform. For online sellers, DTI says complaints may be sent to FTEB at fteb@dti.gov.ph with eco@dti.gov.ph copied. Metro Manila complainants may also use the Consumer CARe portal, email consumercare@dti.gov.ph, or file in person with FTEB. (DTI ECommerce)

Do I need to message the seller first before filing with DTI?

For internet transactions, yes, you should use the seller or platform’s internal redress mechanism first. Under the Internet Transactions Act IRR, the internal mechanism is deemed exhausted if the complaint remains unresolved after seven calendar days.

Can I complain to DTI if I bought through Facebook Marketplace or Instagram?

Yes, if the seller is acting as a business or regularly selling goods or services online. DTI’s E-Commerce FAQ says DTI accommodates complaints for online and offline businesses, even when the merchant is not on major platforms like Lazada, Shopee, or Zalora. (DTI ECommerce)

Can DTI force the seller to refund me?

DTI can facilitate a refund through mediation. If the case proceeds to adjudication and the evidence supports your complaint, DTI can order remedies such as restitution, rescission, refund, replacement, or other appropriate relief under consumer protection laws. In Autozentrum, the Supreme Court discussed DTI’s power to order restitution or rescission and administrative fines in Consumer Act cases. (Supreme Court E-Library)

What if the online seller does not attend DTI mediation?

If the respondent fails or refuses to appear or participate in scheduled mediation, the mediation officer may issue a notice of failure of mediation and submit the case for adjudication. (Supreme Court E-Library)

Can I file against Shopee, Lazada, TikTok Shop, or another platform?

You may include the platform if its acts or omissions are relevant, especially if it handled payment, refund review, delivery, seller verification, or post-purchase support. Under the ITA IRR, the online merchant is primarily liable, but an e-marketplace or digital platform may be subsidiarily or solidarily liable in specific circumstances.

Is a DTI complaint the same as an estafa case?

No. A DTI complaint is a consumer protection and administrative process. Estafa is a criminal offense under the Revised Penal Code. If the seller’s conduct involved fraud, fake identity, or a deliberate scheme to take money without intending to deliver, a criminal complaint may be appropriate in addition to the DTI complaint.

Can I file a DTI complaint without an official receipt?

Yes, but you still need proof of transaction. Online purchases often have order confirmations, payment screenshots, bank records, e-wallet receipts, courier waybills, and chat records. Lack of an official receipt may itself be relevant, but you must still prove that you paid and what the seller promised.

How long does a DTI complaint take?

Simple complaints may settle at mediation within weeks, especially when the seller cooperates. Cases that proceed to adjudication can take longer, often months, depending on evidence, notices, schedules, and the volume of cases at the handling office. The internal redress step for online transactions is considered exhausted after seven calendar days if unresolved.

What if I am abroad and the seller is in the Philippines?

You may file through email or online channels when available. If you need someone in the Philippines to appear, sign, or submit documents for you, prepare written authority or a Special Power of Attorney. If executed abroad, the document may need consular notarization or apostille depending on the country and the receiving office’s requirements.

Key Takeaways

DTI complaints are useful for non-delivery, defective products, fake items, misleading advertisements, warranty refusals, and refund disputes involving online business sellers.
Use the seller or platform’s internal complaint system first. Under the Internet Transactions Act IRR, it is deemed exhausted if unresolved after seven calendar days.
The online merchant or e-retailer is primarily liable, but platforms may be subsidiarily or solidarily liable in specific situations.
Strong evidence matters: proof of payment, order confirmation, screenshots, chat logs, delivery records, product photos, and platform dispute records.
Mediation is mandatory before adjudication. If the seller refuses to participate or no settlement is reached, the case may proceed to DTI adjudication.
For fraud or fake-identity scams, a DTI complaint may be combined with a criminal complaint through the proper cybercrime authorities.
