You should act immediately when an unfamiliar charge from a foreign merchant appears on your Philippine credit card. Block further transactions, report the charge to the card issuer, and submit a documented dispute even if the merchant name is unfamiliar or the amount is still pending. Philippine law gives cardholders specific complaint-handling protections, but strict bank and payment-network deadlines can still affect whether a chargeback succeeds.

What Is an Unauthorized Overseas Credit Card Charge?

An unauthorized charge is a transaction made without the cardholder’s knowledge, consent, or permission. The merchant may be located abroad, while the cardholder and issuing bank are in the Philippines.

Examples include:

A foreign online store charged your card even though you never visited its website.
Your card details were used for purchases in another country while the physical card remained with you.
A merchant charged several small “test transactions” followed by a larger amount.
A compromised app, digital wallet, or online account used your saved card information.
Someone used the card details of a supplementary card without the principal cardholder’s permission.

Not every unfamiliar overseas charge is fraud. The correct dispute reason matters because banks and card networks process different problems differently.

Situation	Proper description
You never made or permitted the purchase	Unauthorized or fraudulent transaction
The same purchase was charged twice	Duplicate billing
You cancelled a subscription but were charged again	Cancelled recurring transaction
You ordered an item but it never arrived	Goods or services not received
You received the wrong or defective item	Goods or services not as described
The merchant charged more than the agreed price	Incorrect transaction amount
The business name on the statement is unfamiliar	Unrecognized merchant descriptor, which must first be verified

A merchant’s statement name may differ from its brand name. Hotels, travel platforms, mobile applications, online marketplaces, and payment processors frequently use a parent company or billing company as the card descriptor.

Check your email, app subscriptions, digital wallets, travel bookings, and family members who have supplementary cards. Do this quickly, but do not delay reporting a genuinely suspicious transaction while trying to identify the merchant.

Your Rights Under Philippine Credit Card Law

The bank must accept and investigate a billing dispute

The principal law governing Philippine credit cards is Republic Act No. 10870, or the Philippine Credit Card Industry Regulation Law.

Under its implementing rules in BSP Circular No. 1003, a credit card issuer must:

Give the cardholder up to 30 calendar days from the statement date to report an error or discrepancy.
Allow the report to be made through written, verbal, or another documented means.
Take action within 10 business days after receiving the notice and relevant documents.
Conduct a thorough investigation and provide a written explanation or correction within 90 days after receiving the notice.
Avoid collecting the contested amount before completing the investigation and explaining its findings, subject to the applicable regulations.
Continue collecting amounts that the cardholder has not disputed.

The 10-business-day period does not necessarily mean the dispute must be resolved within 10 days. The bank may comply by acknowledging the dispute, blocking the card, requesting documents, or opening an investigation. The final investigation may take up to 90 days.

Interest and fees on the disputed amount should be suspended

Republic Act No. 11765, or the Financial Products and Services Consumer Protection Act of 2022, recognizes the financial consumer’s rights to:

Fair and equitable treatment;
Protection of assets against fraud and misuse;
Data privacy and protection; and
Timely handling and redress of complaints.

When a consumer alleges an unauthorized transaction or disputed amount, the financial service provider must, while its final investigation is pending, suspend the imposition of interest, fees, and charges or provide a similar reasonable accommodation. Every covered provider must also maintain a free Financial Consumer Protection Assistance Mechanism, commonly called an FCPAM.

Ask the bank in writing to:

Mark the transaction as disputed.
Suspend interest, late fees, over-limit fees, and other charges attributable to the disputed amount.
Recalculate the minimum amount due, if necessary.
Confirm that the dispute will not be reported as delinquency while under investigation.
Reverse any foreign transaction fee or finance charge if the transaction is ultimately found unauthorized.

A lost or stolen card creates a special issue

RA 10870 states that transactions made before a cardholder reports a card lost or stolen are generally for the cardholder’s account. This makes immediate reporting critical.

However, BSP Circular No. 1003 expressly preserves the cardholder’s right to dispute a pre-report transaction. If the bank’s investigation finds that it was unauthorized or fraudulent, the issuer must correct or reverse the transaction, including related finance charges and fees.

This means that late reporting can weaken a claim, but it does not automatically prevent the cardholder from presenting evidence of fraud.

There is no automatic permanent refund

Filing a dispute does not guarantee that the charge will be permanently removed.

Some banks provide a provisional credit, meaning a temporary reversal while the case is investigated. The credit may later be removed if the merchant submits convincing evidence that the transaction was valid.

The dispute process may involve:

The Philippine issuing bank;
The merchant’s foreign acquiring bank;
The merchant;
A payment network such as Visa, Mastercard, JCB, American Express, or UnionPay; and
A payment processor, digital wallet, travel platform, or marketplace.

The chargeback mechanism is governed by Philippine law, the credit card agreement, the issuer’s procedures, and the applicable card-network rules. These network rules have separate filing and evidence deadlines, so it is unsafe to wait until the end of the statutory 30-day period.

How to Dispute an Unauthorized Overseas Credit Card Charge

1. Lock the card immediately

Use the bank’s mobile application, website, or fraud hotline to temporarily lock or permanently block the card.

Ask the issuer to:

Block online and international transactions;
Remove the card from digital wallets or tokenized payment services;
Replace the card with a new card number;
Stop recurring transactions linked to the compromised credentials, where technically possible; and
Check for pending authorizations that have not yet appeared on the statement.

Cancelling the physical card does not erase an already posted transaction. A separate dispute must still be filed.

2. Report the charge through the bank’s official fraud channel

Call the number printed on the back of the card or use the bank’s verified website or mobile application. Do not rely only on social-media messages.

Record:

The date and time of the call;
The name or identifier of the bank representative;
The dispute or incident reference number;
The exact transactions reported;
The date the card was blocked;
The documents requested; and
The promised response date.

Ask the bank whether each transaction is pending or posted. A pending transaction may disappear on its own, but the bank should still be informed if it appears fraudulent.

3. Submit a written dispute the same day

Even when the bank accepts a telephone report, send a written complaint by email, secure message, or the bank’s prescribed dispute form. Written records prevent later disagreement about when and what you reported.

A clear notice may state:

I dispute the overseas credit card transaction described below. I did not make, authorize, participate in, benefit from, or permit this transaction. My card remained in my possession at the relevant time, if applicable. Please block the compromised card, investigate the transaction, initiate the appropriate chargeback process, suspend interest and fees on the disputed amount, and provide me with a written investigation result.

List every transaction separately:

Transaction date;
Posting date;
Merchant descriptor;
Original foreign-currency amount;
Philippine-peso amount;
Foreign transaction or conversion fee;
Last four digits of the card; and
Reason for dispute.

Never send the full card number, PIN, CVV, password, or one-time password through ordinary email.

4. Use the correct dispute reason

Do not describe an authorized purchase as “fraud” merely because the merchant failed to deliver, refused a refund, or supplied a defective item.

For example:

“I never made this purchase” is an unauthorized-transaction claim.
“I made the purchase, but the item never arrived” is a non-delivery claim.
“I cancelled before renewal” is a cancelled-recurring-payment claim.

Inconsistent explanations are a common reason for denial. A merchant may defeat an unauthorized-use claim by producing your order history, account login, email correspondence, delivery records, or prior transactions.

5. Preserve supporting evidence

Useful evidence depends on the type of transaction.

Evidence	Why it helps
Credit card statement or app screenshot	Identifies the amount, date, and merchant descriptor
Fraud report and bank reference number	Proves prompt notification
Proof that the card was in your possession	Supports a card-cloning or card-data theft claim
Passport stamps, flight records, or work attendance	Shows you were not in the country where a card-present purchase occurred
Email and text-message history	Shows whether you received an OTP, confirmation, or merchant message
Device and account login history	May show an unfamiliar device, location, or account takeover
Subscription cancellation confirmation	Supports a cancelled-recurring-transaction dispute
Merchant correspondence	Proves that you requested cancellation, delivery, correction, or a refund
Delivery tracking	Shows that goods were not delivered to you
Police or NBI report	Supports serious fraud, identity theft, or repeated unauthorized use

Keep original files. Do not rely only on cropped screenshots that omit the date, sender, URL, or transaction details.

6. Pay the undisputed portion of the bill

Do not automatically stop paying the entire credit card bill.

The issuer may continue collecting valid, undisputed charges. Failure to pay them may result in:

Late-payment fees;
Finance charges;
Account suspension;
Collection calls; or
Negative credit reporting.

Ask the bank to confirm the correct amount you must pay while the disputed transaction is under investigation. If the bank’s statement still includes the disputed amount in the minimum due, object in writing and request recalculation or another reasonable accommodation under RA 11765.

7. Report serious fraud to law enforcement

A police or cybercrime report is not always required before a bank accepts a credit card dispute. It becomes particularly useful when:

The amount is substantial;
Several banks or accounts were compromised;
Identity documents were stolen;
The fraud involved phishing, malware, account takeover, or social engineering;
The bank requests a formal report; or
You intend to pursue the person responsible.

Unauthorized use of card information may constitute access-device fraud under Republic Act No. 8484, as amended by Republic Act No. 11449.

Complaints involving computer-related fraud may be brought to the NBI Cybercrime Division or another appropriate investigative unit. The NBI provides an online complaint channel and investigative assistance for victims of computer crimes. (National Bureau of Investigation)

A criminal complaint and a credit card dispute are separate processes. Filing with the NBI does not automatically reverse the charge, and a bank chargeback does not automatically result in criminal prosecution.

What Happens During the Bank’s Investigation?

The issuer will usually determine:

Whether the transaction was card-present, online, recurring, or merchant-initiated.
Whether a chip, magnetic stripe, contactless function, digital token, CVV, or 3-D Secure authentication was used.
Whether an OTP or in-app approval was generated.
Whether the transaction matches your previous spending pattern.
Whether the merchant has delivery records, account records, or other proof.
Whether the claim was filed within the bank and card-network deadlines.

The bank may ask you to sign an affidavit denying the transaction. Read it carefully. Confirm that the dates, amounts, and statements are accurate before signing.

No OTP does not automatically prove fraud

Many legitimate transactions do not require an OTP. Examples include:

Recurring subscriptions;
Merchant-initiated transactions;
Card-on-file purchases;
Low-risk transactions exempted from additional authentication;
Digital-wallet token transactions; and
Transactions processed under a payment network’s risk-based authentication system.

The absence of an OTP can support your account, but it is rarely conclusive by itself.

An OTP does not always prove genuine consent

A transaction may still be disputed when an OTP was obtained through phishing, impersonation, malware, or another scam. However, the bank will closely examine how the OTP was generated and used.

Be precise about what happened. Do not simply deny receiving an OTP if you actually disclosed or entered one after being deceived. Explain the social-engineering method, impersonation, false website, or fraudulent call and provide evidence.

A foreign-currency reversal may create conversion issues

For an overseas transaction, identify both:

The original transaction amount and currency; and
The peso amount charged to the account.

If the dispute succeeds, check whether the reversal includes:

The entire posted peso amount;
The foreign transaction or cross-border fee;
Finance charges attributable to the transaction; and
Any exchange-rate difference that remains on the account.

Raise any shortage as a separate billing discrepancy.

What to Do If the Bank Denies the Dispute

Request a detailed written explanation

Do not accept a bare statement that the transaction was “authenticated” or “valid.”

Ask the bank to identify:

The authentication method used;
Whether the transaction was card-present, e-commerce, recurring, or tokenized;
Whether 3-D Secure or an OTP was used;
The date, time, and channel of authentication;
Whether the merchant submitted delivery or account-access evidence;
The reason the bank rejected your affidavit or other documents;
The contractual or card-network basis for the denial; and
Whether reconsideration, pre-arbitration, or another review remains available.

Respond point by point. Attach new evidence and correct any misunderstanding.

Escalate the complaint to the BSP

A consumer must first report the concern to the bank’s FCPAM or customer-service channel. If the bank does not act within a reasonable period, gives an inadequate response, or denies the claim, the complaint may be escalated to the Bangko Sentral ng Pilipinas.

The BSP Consumer Assistance Mechanism is a second-level recourse. Complaints may be submitted through the BSP Online Buddy chatbot. Consumers without access to the chatbot may use the BSP Complaint/Inquiry/Reply form and email it to the address stated on the official BSP consumer assistance page.

Attach:

Your complaint to the bank;
The bank’s acknowledgment and final response;
Dispute forms;
Statements showing the charges;
Evidence supporting your position;
A timeline of events; and
The specific resolution requested.

Do not send the BSP your PIN, password, CVV, full card number, passport, or complete identification document unless the BSP specifically requests an appropriately redacted or secure submission. The BSP’s published procedure requires proof that the consumer first used the bank’s complaint mechanism.

BSP mediation

Under BSP Circular No. 1169, the BSP Consumer Assistance Mechanism must generally be completed before mediation or adjudication.

Mediation is voluntary and confidential. A BSP mediator helps the consumer and bank negotiate a settlement but does not impose a result. Proceedings are normally conducted through online video conference, although face-to-face mediation may be allowed for good cause.

The prescribed mediation period is generally 30 days from the initial mediation conference, subject to extension for meritorious reasons agreed upon by the parties.

BSP adjudication

The BSP may adjudicate certain financial-consumer claims that are:

Purely civil in nature;
Directed against a BSP-supervised institution; and
Limited to payment or reimbursement of money not exceeding ₱10 million, excluding legal interest, attorney’s fees, and costs.

The formal complaint must be verified, supported by evidence, and accompanied by a certification against forum shopping. It may be filed personally or through registered mail or courier with the BSP Consumer Complaints Resolution Office at the BSP Head Office. The applicable rules require copies for the respondent and the BSP.

A consumer who has already filed the same dispute before a court or another body must disclose that fact. Parallel proceedings may cause dismissal or create a forum-shopping issue.

Common Reasons Overseas Card Disputes Fail

The complaint was filed too late

The 30-day period under the Philippine credit card rules is counted from the statement date. Separate card-network and bank-contract deadlines may also apply.

Report the transaction as soon as it appears. Do not wait for the next statement if the bank’s app already shows the charge.

The merchant name was merely unfamiliar

A valid transaction may appear under:

A payment processor;
A hotel management company;
An airline’s corporate name;
An app-store billing entity;
A foreign parent company; or
A marketplace rather than the actual seller.

Ask the bank for the merchant category, location, and available descriptor information before insisting that the charge is fraudulent.

A family member or supplementary cardholder made the purchase

The bank may deny the claim if a spouse, child, employee, or supplementary cardholder used the account with actual or apparent permission.

Confirm who had access to:

The physical card;
Card photographs;
Saved browser details;
Shopping accounts;
Digital wallets; and
The phone receiving OTPs.

The transaction was a recurring payment

Replacing the card does not always stop a merchant from receiving updated account credentials through card-network services.

Cancel the subscription directly with the merchant and retain proof. If the merchant charges again, dispute it as a cancelled recurring transaction rather than claiming that no relationship ever existed.

The consumer used inconsistent explanations

A claim may be weakened when the cardholder initially says, “I do not recognize the merchant,” then later admits making the purchase but complains about quality or delivery.

Correct an honest mistake promptly, but use the dispute category that matches the facts.

The merchant already issued a refund

A merchant refund may take several business days or billing cycles to appear. Do not obtain both a merchant refund and a chargeback for the same amount.

Inform the bank immediately if the merchant promises or issues a refund. Keep the dispute open only when necessary to protect the filing deadline, and disclose the pending refund.

Special Issues for OFWs, Foreigners, and Cardholders Abroad

Philippine-issued cards remain subject to Philippine complaint procedures

An OFW or foreign national using a credit card issued by a BSP-supervised Philippine institution may generally use the bank’s FCPAM and BSP complaint channels. RA 11765 defines a financial consumer broadly and does not limit its protections to Filipino citizens. The controlling issue is whether the provider is subject to the relevant Philippine financial regulator.

Foreign-issued cards are different

If the card was issued by a bank outside the Philippines, BSP jurisdiction will ordinarily not apply merely because the cardholder or merchant has some connection to the Philippines.

The complaint should normally be filed with:

The foreign issuing bank;
The applicable card network;
The financial regulator in the issuing bank’s country; or
The dispute system of the marketplace or payment provider.

Documents signed abroad may need authentication

Routine bank disputes are usually handled electronically. Formal mediation, adjudication, representation, or affidavits may require notarized documents.

A cardholder abroad who appoints someone in the Philippines may need a Special Power of Attorney. Depending on the country, the document may be:

Notarized at a Philippine embassy or consulate; or
Notarized locally and apostilled by the competent authority of a country participating in the Apostille Convention.

For documents originating in a non-Apostille country, consular authentication or another legalization process may be required. Requirements and fees vary by country and document. The DFA’s official guidance explains the use of apostilles and consular notarization for private documents such as affidavits and Special Powers of Attorney. (Philippine Embassy)

The bank’s dispute form;
Copies of emails and secure messages;
Call dates and reference numbers;
Merchant correspondence;
Proof of cancellation or non-delivery, when applicable;
Evidence of your location and possession of the card;

Frequently Asked Questions

Can the bank require me to pay an unauthorized charge while investigating?

The bank may collect undisputed charges, but RA 11765 requires the suspension of interest, fees, and charges on an alleged unauthorized transaction or a similar reasonable accommodation while the final investigation is pending. Ask the bank to confirm in writing how much you must pay.

Does the 30-day deadline run from the purchase date?

The BSP credit card rule measures the reporting period from the statement date, not merely the transaction date. Nevertheless, report the transaction immediately because bank and card-network deadlines may be more restrictive in particular cases.

Can I dispute a transaction that did not require an OTP?

Yes. The absence of an OTP does not prevent a dispute. Some legitimate transaction types do not use OTP authentication, so the bank will review other transaction and merchant evidence.

What if I entered an OTP because a scammer deceived me?

Explain exactly how the deception occurred. Provide screenshots, messages, call records, fake website details, and any criminal complaint. The presence of an OTP may make the case more difficult, but it does not prevent an investigation into phishing, impersonation, malware, or social engineering.

Do I have to contact the overseas merchant first?

For a clearly unauthorized transaction, report it to the bank immediately. You do not need to delay the fraud report while waiting for an overseas merchant to respond. For delivery, cancellation, refund, or quality disputes, proof that you attempted to resolve the problem with the merchant is often important.

Will cancelling my card automatically reverse the charge?

No. Cancelling or replacing the card prevents or limits future use. Each posted unauthorized transaction must still be identified and disputed.

Is a police or NBI report required?

Not in every case. Banks may initially accept a signed dispute form or affidavit. A law-enforcement report is more useful for substantial losses, identity theft, repeated fraud, account takeover, or cases where the bank specifically requests one.

Can I dispute a foreign subscription charge?

Yes, but determine whether you originally authorized the subscription. If you subscribed and later cancelled, submit the cancellation confirmation and classify the charge as a cancelled recurring transaction rather than an entirely unauthorized purchase.

Can a foreigner file a complaint with the BSP?

A foreigner may generally use BSP consumer channels when the disputed credit card was issued by a BSP-supervised Philippine institution. Nationality is less important than the identity and regulatory status of the financial service provider.

What should I do if the bank says the transaction was “valid” without explaining why?

Request the complete written investigation result and the authentication or merchant evidence relied upon. Seek reconsideration through the bank’s FCPAM, then elevate the complaint to the BSP Consumer Assistance Mechanism if the explanation remains inadequate.
