When an online seller takes your payment and then disappears, blocks you, sends a fake item, or refuses a lawful refund, you do not have to rely only on angry messages or public posts. In the Philippines, you can file a consumer complaint with the Department of Trade and Industry (DTI), especially if the seller is acting as an online merchant, e-retailer, marketplace seller, or business offering goods or services to the public. This guide explains when DTI can help, what evidence to prepare, how to file the complaint, what happens during mediation, and when you should also report the matter to the NBI or police for possible online fraud.
Can You File a DTI Complaint Against an Online Scam Seller?
Yes, you can file a DTI complaint against an online scam seller when the transaction involves a consumer purchase of goods or services from a seller doing business online.
This includes many common situations such as:
- You paid for an item on Facebook Marketplace, Instagram, TikTok Shop, Shopee, Lazada, a website, or another online platform, but the seller never delivered it.
- The seller delivered a fake, defective, wrong, or materially different item.
- The seller promised a refund, replacement, or return, then ignored or blocked you.
- The seller used misleading photos, false claims, fake reviews, or a fake business identity.
- The seller refused to issue a receipt, invoice, delivery details, or legitimate contact information.
DTI’s Fair Trade Enforcement Bureau accommodates complaints involving both online and offline businesses, and DTI specifically directs complaints against online sellers to its Fair Trade Enforcement Bureau email, with the e-commerce office copied when appropriate. (DTI ECommerce)
However, not every “online scam” is purely a DTI matter. If the seller used a fake identity, immediately withdrew the money, hacked an account, used phishing links, or ran a clear fraud scheme, you should also consider reporting the matter to law enforcement, such as the National Bureau of Investigation Cybercrime Division or the police, because DTI’s consumer process is different from a criminal investigation.
DTI Complaint vs. Criminal Complaint: Know the Difference
A DTI complaint is mainly a consumer protection remedy. It is useful when you want:
- A refund
- Replacement of the item
- Repair
- Cancellation of the transaction
- Return of payment
- Mediation with the seller
- Administrative action against a business
- Possible takedown or enforcement action under e-commerce laws
A criminal complaint is different. It is used when the seller’s conduct may amount to a crime, such as estafa, which is swindling under Article 315 of the Revised Penal Code. Article 315 punishes a person who defrauds another through the means listed in the law, including deceit or fraudulent representations. (Lawphil)
If the fraud was committed through the internet, computer systems, social media, electronic messages, or other information and communications technology, Republic Act No. 10175, or the Cybercrime Prevention Act of 2012, may also become relevant because crimes under the Revised Penal Code committed through ICT are covered by the cybercrime law. (Lawphil)
In practical terms:
| Problem | Best first step |
|---|---|
| Seller is a known online shop but refuses refund or replacement | File a DTI complaint |
| Marketplace seller sent wrong, fake, or defective item | Use platform redress first, then file with DTI if unresolved |
| Seller disappeared after payment and identity appears fake | Report to DTI, but also file with NBI or police |
| You clicked a phishing link or your e-wallet/bank was accessed | Report immediately to bank/e-wallet and law enforcement |
| One private person sold you a secondhand item once | DTI jurisdiction may be limited; consider civil or criminal remedies depending on facts |
Legal Basis: Your Rights Against Online Scam Sellers
Consumer Act of the Philippines
The main consumer protection law is Republic Act No. 7394, also known as the Consumer Act of the Philippines. Its policy is to protect consumer interests and promote the general welfare, including protection against deceptive, unfair, and unconscionable sales acts and practices. (Supreme Court E-Library)
For online scam seller situations, this matters because misleading product descriptions, false advertisements, fake claims, and refusal to honor basic consumer rights may fall under consumer protection rules. The law also allows the concerned department to act on consumer complaints and establish procedures for investigating and responding to them. (ASEAN Consumer)
Internet Transactions Act of 2023
Republic Act No. 11967, or the Internet Transactions Act of 2023, is especially important for online seller complaints. It covers business-to-business and business-to-consumer internet transactions within DTI’s mandate when one party is situated in the Philippines, or when a digital platform, e-marketplace, e-retailer, or online merchant avails of the Philippine market. It excludes purely consumer-to-consumer transactions. (Supreme Court E-Library)
The law gives DTI and its E-Commerce Bureau powers relevant to online complaints, including receiving or referring consumer complaints, coordinating with other agencies, and using an online dispute resolution system. (Supreme Court E-Library)
It also recognizes that DTI may issue compliance orders, takedown orders, and other enforcement measures in proper cases, subject to the requirements of the law. (Supreme Court E-Library)
Duties of Online Merchants and E-Retailers
Under the Internet Transactions Act, online merchants and e-retailers have specific obligations. They must give accurate information about the product or service, price, and relevant transaction details. They must also ensure that the goods received by the consumer are of the same condition, type, quantity, and quality described, and are fit for the purpose represented by the merchant. (Supreme Court E-Library)
Online merchants are also required to publish identifying information such as their corporate or trade name, physical or registered address, contact details, and other required information. They must issue paper or electronic invoices or receipts, and they must maintain an internal redress mechanism for consumer complaints. (Supreme Court E-Library)
A key practical rule: where the law requires use of the seller’s internal redress mechanism, that mechanism is considered exhausted after seven calendar days from filing if the complaint remains unresolved. The law also states that the e-retailer or online merchant is primarily liable for indemnifying the consumer in a civil action or administrative complaint arising from the internet transaction. (Supreme Court E-Library)
Liability of Marketplaces and Digital Platforms
Online marketplaces and digital platforms are not automatically liable for every bad seller. But they can become responsible in specific situations, such as when they fail to exercise ordinary diligence, fail to remove unlawful goods after notice, or fail to provide required mechanisms and information under the law. (Supreme Court E-Library)
This is why, when filing a complaint, you should include not only the seller’s details but also the platform used, the order number, the shop link, and screenshots showing whether you used the platform’s official complaint, return, refund, or chat system.
Civil Code Remedies
The Civil Code may also apply. Articles 19, 20, 21, and 22 require people to act with justice, honesty, good faith, and fairness, and prohibit causing damage contrary to law, morals, good customs, or public policy. They also prevent unjust enrichment, which means a person should not unfairly benefit at another’s expense. (Lawphil)
In sales transactions, Civil Code rules on warranties and hidden defects may also matter when the item delivered is defective, fake, unusable, or different from what was promised. (Law Library - Legal Resource PH)
Electronic Evidence
Screenshots, chat messages, electronic receipts, transaction confirmations, order pages, and emails can be important evidence. Philippine law recognizes electronic documents and electronic signatures under the Electronic Commerce Act, and the Supreme Court’s Rules on Electronic Evidence allow electronic documents to be admitted if properly authenticated. (Lawphil)
Do not rely on screenshots alone if you can preserve stronger proof. Save the original messages, transaction IDs, URLs, email headers, delivery records, and bank or e-wallet confirmations.
Before Filing: Preserve Your Evidence Properly
Before sending your DTI complaint, organize your evidence. Many consumer complaints fail or get delayed not because the buyer is wrong, but because the complaint is incomplete, confusing, or unsupported.
Prepare the following:
| Evidence | Why it matters |
|---|---|
| Seller’s full name, shop name, page name, username, mobile number, email, and address | Helps DTI identify and notify the seller |
| Product listing screenshots | Shows what was promised |
| Chat messages | Shows representations, promises, refund refusal, or blocking |
| Proof of payment | Shows amount, date, account number, reference number, or recipient |
| Order confirmation, invoice, receipt, or waybill | Links the transaction to the seller or platform |
| Photos or videos of the item received | Useful for fake, defective, damaged, or wrong-item complaints |
| Platform complaint records | Shows you tried the app or marketplace process first |
| Demand for refund or replacement | Shows you gave the seller a chance to fix the issue |
| Seller’s deletion, blocking, or account changes | Supports bad faith or possible fraud |
Practical tips:
- Take screenshots that show the date, time, account name, URL, and full conversation.
- Save the seller’s profile link before it disappears.
- Download your e-wallet or bank transaction history.
- Do not crop out important context.
- Do not delete the chat even if you already took screenshots.
- If the amount is significant, consider executing a sworn statement or affidavit for law enforcement use.
- If you are abroad, keep Philippine-time timestamps and payment records clear.
Step-by-Step Guide: How to File a DTI Complaint Against an Online Scam Seller
1. Try the seller or platform’s complaint process first
If you bought through a marketplace or app, use the platform’s official return, refund, dispute, or complaint system immediately.
For example, depending on the platform, you may need to:
- Click “Return/Refund”
- Report the shop
- Open a dispute
- Use buyer protection
- Contact customer support through the app
- Refuse to confirm receipt if the item is wrong or missing
- Keep the transaction inside the platform instead of moving to private chat
Under the Internet Transactions Act, the internal redress mechanism may be considered exhausted if the complaint remains unresolved after seven calendar days. (Supreme Court E-Library)
This does not mean you must wait forever. If the seller is obviously fraudulent, the account disappeared, or there is risk that the money will be gone, you can prepare your DTI and law enforcement reports right away.
2. Identify the correct respondent
Your complaint should clearly state who you are complaining against.
Include as many of these as possible:
- Registered business name
- Online shop name
- Seller’s real name, if known
- Social media page name
- Marketplace shop link
- Mobile number
- Email address
- Pickup, delivery, or return address
- Bank or e-wallet account name
- Platform used
- Courier details
- Order number or transaction reference
If you do not know the seller’s real name, say so clearly. Provide the information you have and explain how the seller represented themselves.
For marketplace transactions, you may also mention the platform if the platform failed to act on your complaint, failed to preserve seller information, or ignored a valid refund or takedown request.
3. Prepare a clear complaint letter
A DTI complaint does not need to sound like a court pleading, but it should be organized.
Your complaint should answer these questions:
- Who are you?
- Who is the seller?
- What did you buy?
- When did you order and pay?
- How much did you pay?
- What exactly went wrong?
- What did the seller promise?
- What did you do to resolve it?
- What response did the seller or platform give?
- What remedy are you asking for?
Possible remedies include:
- Full refund
- Replacement with the correct item
- Repair
- Cancellation of transaction
- Reimbursement of shipping fee
- Removal of misleading listing
- Issuance of official receipt or invoice
- Administrative action against the seller
4. File your complaint with DTI
For Metro Manila complainants, DTI states that complaints may be submitted through its online portal, by email using the duly accomplished complaint form or complaint letter, or in person to the Fair Trade Enforcement Bureau. The portal mentioned by DTI is the Consumer Care system, and DTI also lists consumercare@dti.gov.ph for complaint submissions. (Fair Trade Enforcement Bureau)
For online seller complaints, DTI’s e-commerce FAQ directs consumers to send complaints to fteb@dti.gov.ph and copy eco@dti.gov.ph. (DTI ECommerce)
You may also contact or visit the DTI Fair Trade Enforcement Bureau at the Trade and Industry Building, 361 Sen. Gil J. Puyat Avenue, Makati City. DTI lists FTEB contact details including telephone number (02) 7215-1165, mobile number 0917 137 3796, and email fteb@dti.gov.ph. (Fair Trade Enforcement Bureau)
If you are outside Metro Manila, you may file with the DTI Regional Office or Provincial Office connected to your residence, the seller’s residence or business location, or where the transaction was done. DTI’s mediation and adjudication rules recognize venue through FTEB in the National Capital Region and DTI regional or provincial offices in proper cases.
5. Wait for DTI action and attend mediation
DTI consumer complaints generally go through mediation first. Mediation is a meeting facilitated by DTI where the buyer and seller try to settle the dispute.
Under DTI Department Administrative Order No. 20-02, Series of 2020, mediation is mandatory for consumer complaints involving the Consumer Act and Fair Trade Laws as a condition before formal adjudication. DTI’s rules provide for issuance of a Notice of Mediation within three working days in covered cases. (Fair Trade Enforcement Bureau)
The mediation period should generally be completed within seven working days from service of the Notice of Mediation, extendible for a maximum of ten working days. Parties may appear personally or through an authorized representative.
During mediation:
- Be calm and factual.
- Bring or attach all evidence.
- State the exact remedy you want.
- Do not agree to vague promises.
- If settlement is reached, make sure it is written.
- Ask that the settlement include specific dates, amounts, and consequences for non-compliance.
6. If the seller does not appear or there is no settlement
If mediation fails, the case may proceed depending on the circumstances. DTI rules provide that if there is no settlement or a party fails to appear, a Certificate to File Action may be issued. If the complainant fails or refuses to appear twice, the complaint may be considered withdrawn.
For formal adjudication, the complaint must be more complete. DTI rules require, among others, a verified complaint, names and addresses of the parties, allegations and material facts, supporting evidence, reliefs requested, a Certificate to File Action, and a certificate of non-forum shopping.
After the case is assigned for adjudication, the parties may be directed to file position papers. DTI rules provide a non-extendible period of ten working days from receipt of the Notice of Adjudication for position papers.
7. Report possible online fraud to NBI or police
If the seller disappeared, used a fake name, used multiple scam accounts, received money through another person’s account, or appears to be part of a fraud operation, report the matter to law enforcement.
The NBI Cybercrime Division handles investigative assistance for victims of computer crimes. NBI’s Citizens Charter describes a process where complainants may proceed to the Cybercrime Division, file a complaint or request for investigation, undergo preliminary interview, execute sworn statements, and submit affidavits and evidence. The listed government fees for that process are none. (National Bureau of Investigation)
NBI also lists the Cybercrime Division email as ccd@nbi.gov.ph. (National Bureau of Investigation)
For urgent matters, also report to:
- Your bank or e-wallet provider
- The platform used
- The courier, if delivery fraud is involved
- The nearest police station or appropriate cybercrime unit
- The SIM, social media, or payment service provider, if account misuse is involved
Where to File: DTI Offices and Channels
| Situation | Where to file or report | Practical note |
|---|---|---|
| Consumer complaint against online seller in Metro Manila | DTI Consumer Care portal, consumercare@dti.gov.ph, or FTEB |
Attach complaint letter and evidence |
| Online seller complaint involving e-commerce | fteb@dti.gov.ph, copy eco@dti.gov.ph |
Useful for Facebook, marketplace, app, or website sellers |
| Complaint outside Metro Manila | DTI Regional Office or Provincial Office | File where you live, where the seller is, or where the transaction occurred |
| Possible estafa or cybercrime | NBI Cybercrime Division or police | Use this when seller identity is fake, money is gone, or there is organized fraud |
| Bank or e-wallet payment | Bank/e-wallet fraud or customer protection channel | Request investigation, account freezing if still possible, and transaction trace |
| Marketplace transaction | Platform dispute system | Use this first when buyer protection deadlines are running |
Documents to Prepare
Prepare both digital and printable copies if possible.
| Document or evidence | Needed for DTI? | Needed for NBI/police? |
|---|---|---|
| Valid government ID | Yes | Yes |
| Complaint letter | Yes | Helpful |
| Screenshots of listing and seller profile | Yes | Yes |
| Complete chat history | Yes | Yes |
| Proof of payment | Yes | Yes |
| Bank or e-wallet reference number | Yes | Yes |
| Order confirmation or waybill | Yes | Helpful |
| Photos/videos of item received | Yes, if wrong/defective/fake item | Helpful |
| Platform dispute record | Yes, if marketplace transaction | Helpful |
| Sworn statement or affidavit | Sometimes | Commonly required |
| Authorization letter or special power of attorney | If representative will appear | If representative will file or follow up |
If you are an OFW or foreigner filing from abroad, email and online filing may be the easiest first step. If someone in the Philippines will attend mediation, sign an authorization letter and attach IDs. For more formal proceedings or court-related documents signed abroad, apostille or consular authentication may be required depending on how the document will be used.
How Long Does a DTI Complaint Take?
The timeline depends heavily on whether the seller can be identified and served with notice.
| Stage | Usual or rule-based timing |
|---|---|
| Internal platform redress | Considered exhausted after seven calendar days if unresolved under the Internet Transactions Act |
| DTI Notice of Mediation | DTI rules provide for notice within three working days in covered cases |
| Mediation period | Generally completed within seven working days from service, extendible up to ten working days |
| If no settlement | Certificate to File Action may be issued |
| Formal adjudication position paper | Ten working days from receipt of Notice of Adjudication |
| Criminal investigation | Varies depending on evidence, traceability of accounts, and cooperation of banks/platforms |
The most common bottlenecks are:
- Seller used a fake name.
- Seller gave no physical address.
- Seller cannot be served with notice.
- Buyer has only cropped screenshots.
- Payment was sent outside the marketplace protection system.
- Buyer waited too long before reporting to bank or platform.
- The account was deleted before screenshots were saved.
Common Mistakes That Hurt DTI Complaints
Paying outside the platform
Scammers often ask buyers to pay by direct bank transfer, e-wallet, crypto, or “friends and family” style payments outside official checkout. This weakens buyer protection and makes recovery harder.
Not saving the seller’s profile link
A screenshot of a name is helpful, but a profile URL, shop URL, order number, and transaction ID are better. Sellers can change display names quickly.
Filing a vague complaint
Avoid saying only “I was scammed.” State the facts:
- “On March 3, 2026, I ordered one original brand-new phone advertised as ___.”
- “I paid ₱18,500 through GCash to account name ___ with reference number ___.”
- “The seller promised delivery within three days.”
- “No item was delivered, and the seller blocked me on March 7, 2026.”
- “I am requesting a full refund of ₱18,500 and appropriate action.”
Waiting too long
Report quickly. Delay can make it harder to freeze funds, trace accounts, preserve marketplace data, or locate the seller.
Confusing DTI mediation with criminal prosecution
DTI can help with consumer remedies and administrative enforcement. It does not replace a criminal complaint for estafa, identity fraud, phishing, hacking, or organized scams.

[Your Full Name]Special Situations
The seller is on Facebook, Instagram, or TikTok
You may still file a DTI complaint if the seller is acting as an online merchant or business. DTI’s e-commerce guidance recognizes online merchants as persons or entities who sell goods or services directly through the internet. (DTI ECommerce)
But if it was a purely private, one-time consumer-to-consumer sale, DTI’s jurisdiction may be more limited. You may still report the facts, but you should also consider civil or criminal remedies if there was fraud.
The seller is abroad
The Internet Transactions Act may apply when the online merchant, e-marketplace, or digital platform avails of the Philippine market and has minimum contacts with the Philippines. (Supreme Court E-Library)
In practice, enforcement is harder if the seller has no Philippine presence. Start with the platform, payment provider, DTI, and law enforcement if there is fraud. Preserve all transaction data because banks, e-wallets, platforms, and investigators may need exact reference numbers.
The platform says it is not responsible
Do not automatically accept that answer. Under the Internet Transactions Act, liability depends on the platform’s role and conduct. A platform may face subsidiary or solidary liability in certain situations, such as failure to exercise ordinary diligence or failure to remove prohibited or unlawful goods after notice. (Supreme Court E-Library)
When complaining, include proof that you notified the platform and show how it responded.
The seller says “no refund, no return”
A “no refund, no return” statement does not excuse fraud, false advertising, defective goods, wrong items, or failure to deliver. A seller cannot use a store policy to defeat mandatory consumer rights.
The seller sent a cheap item instead of the real product
This is common in online scams. Keep the packaging, waybill, item, photos, and unboxing video if available. Do not throw away the item until the complaint is resolved because it may be evidence.
Frequently Asked Questions
Can I file a DTI complaint against a Facebook seller?
Yes, if the Facebook seller is acting as an online merchant or business seller. Include the page link, seller profile, chat history, proof of payment, product listing, and any refund request. If the seller used a fake identity or disappeared after payment, also report to NBI or police.
Can DTI force the seller to refund me?
DTI mediation can result in a written settlement for refund, replacement, repair, or other remedy. If mediation fails, formal adjudication or other legal remedies may follow. Under the Internet Transactions Act, online merchants and e-retailers are primarily liable to indemnify consumers in covered internet transactions. (Supreme Court E-Library)
Should I file with DTI or NBI?
File with DTI for consumer remedies against a seller or business. File with NBI or police when there is possible estafa, identity fraud, phishing, hacking, fake accounts, or organized online scam activity. In many serious online scam cases, you may need to do both.
What if I only have screenshots?
Screenshots are helpful, but strengthen your case with original chat records, URLs, transaction IDs, bank or e-wallet receipts, platform order numbers, waybills, and seller profile links. Electronic documents may be recognized as evidence if properly authenticated. (Lawphil)
What if the seller is not DTI-registered?
You can still file a complaint using the information you have. Lack of registration may make the seller harder to trace, but it does not automatically defeat your complaint. Provide the seller’s account name, mobile number, e-wallet or bank details, social media link, and delivery information.
How long does DTI mediation take?
DTI rules provide that mediation should generally be completed within seven working days from service of the Notice of Mediation, with a possible extension of up to ten working days. Delays often happen when the seller cannot be served, gives a wrong address, or refuses to participate.
Do I need a lawyer to file a DTI complaint?
For DTI mediation, ordinary consumers usually file and appear without a lawyer. For formal adjudication, a large claim, repeated scams, or possible criminal prosecution, legal assistance may help organize evidence and remedies.
Is there a deadline to file?
File as soon as possible. Under the Internet Transactions Act, an action for damages must be filed within two years from the time the cause of action arose. Other civil, administrative, or criminal remedies may have different prescriptive periods. (Supreme Court E-Library)
Can an OFW or foreigner file a DTI complaint from abroad?
Yes, if the transaction falls within Philippine consumer or internet transaction rules. Use DTI’s online or email channels where available. If someone will appear for you in the Philippines, prepare written authorization and copies of IDs. For formal proceedings, documents signed abroad may need apostille or consular authentication depending on their use.
Key Takeaways
- File a DTI complaint when an online seller acting as a business refuses refund, delivers fake or wrong goods, fails to deliver, or uses misleading sales practices.
- Use the platform’s refund or dispute process first when applicable, but preserve evidence immediately.
- Send online seller complaints to DTI FTEB and copy the e-commerce office when appropriate.
- Prepare clear evidence: seller identity, listing, chat history, proof of payment, order records, waybills, and refund requests.
- DTI mediation is mandatory for covered consumer complaints before formal adjudication.
- If the seller used a fake identity, disappeared after payment, or appears to have committed fraud, also report to NBI or police.
- Act quickly because deleted accounts, withdrawn funds, expired platform protection periods, and missing evidence can make recovery much harder.
