Unrecognised Card Transactions and Payment Disputes: How Disputes Work

Unrecognised card transactions and payment disputes follow a fairly clear path: the card issuer first, then the formal objection steps set out in the card law, and finally the consumer arbitration committees and courts. This guide explains that path in general terms for visitors using a card in Istanbul, whether the card was issued in Turkey or abroad.

It is information, not legal advice. Deadlines, thresholds and procedures are set by law and by card-network rules, and they change and depend on the card, the issuer and the facts. No fees or limits are listed here. Visitors also meet currency conversion offers at terminals. The entries describe who does what, which documents are usually asked for and what to ask the issuer.

How We Chose

The nine entries follow a dispute from the first check of a statement to the court route. They rest on the text of the Bank Cards and Credit Cards Law, the Consumer Protection Law and the public descriptions of the bodies involved.

• The order is a sequence, not a ranking and not a recommendation.
• No issuer or bank is named.
• Card-network and issuer rules differ and are not summarised here.

The sanctions rules of the reader’s own country may restrict the use of Turkish banks and payment services, and readers need to check this themselves with their own bank.

1. Checking Statements and Notifications – Spotting a problem

Card transactions are visible on statements and often through app or SMS notifications. An item can look unrecognised because of a merchant name that differs from the shop's trading name, a duplicate charge, a different amount or a payment never authorised. Checking the date and place first separates these cases before a formal dispute begins.

Good to know: Statements and app histories list merchant names and dates.

Tip: The merchant descriptor on a statement can differ from the venue name, which explains many unfamiliar items.

2. The Card Issuer as First Contact – First step

The issuer, meaning the bank that gave out the card, is the first contact for any disputed item. For a card issued abroad this is the home bank, even when the payment happened in Turkey. Under the card law, an issuer must answer a cardholder's complaint in writing, with reasons, within a short deadline.

Good to know: The issuer's app, customer line or branch handles disputes.

Tip: A dispute is easier to follow when the date, amount and merchant of each item are listed.

3. Objection Windows on Statements – Time limits

The card law gives the cardholder a limited window to object to statement items after the payment due date. A statement not disputed in time becomes final between the card holder and the issuer, though the right to go to court under general rules is not removed. The exact window is in the law and in the issuer's terms.

Good to know: Applies to credit card statements issued in Turkey.

Tip: Foreign issuers follow their own terms and their own national rules.

4. Who Must Prove What – Burden of proof

The card law places the burden of proving that a transaction was correctly recorded on the issuer when the dispute concerns a recording error. For card-not-present purchases made by phone, online or by order form, the merchant bears the burden of proof. Merchants also carry duties to check card authenticity and identity where required.

Good to know: Relevant for online and phone purchases.

Tip: Order confirmations and merchant messages are useful evidence in these cases.

5. Authorised, Unauthorised and Disputed Purchases – Types of dispute

A transaction can be unauthorised, for example after a card is lost or stolen, or authorised but disputed, for example when goods are not delivered or a service differs from the description. These cases follow different rules, and the issuer asks different questions in each. The card law caps liability for unauthorised use after loss or theft, with exceptions for gross negligence or failure to report.

Good to know: The issuer's dispute form usually asks which type applies.

Tip: A merchant refund request in writing, kept as evidence, supports a later dispute over goods or services.

6. Card Network Dispute Processes – Chargebacks in general

Card networks run dispute procedures between issuers and merchants' banks, often called chargebacks. Individuals do not use them directly; the issuer decides whether to start one and sets its own timelines and evidence requirements. Outcomes are not certain and depend on the facts and on network rules that change. Receipts and merchant replies are what issuers commonly ask for.

Good to know: Handled between banks; the cardholder deals with the issuer.

Tip: The issuer states the documents it needs and the time it takes.

7. Currency Conversion at the Terminal – Common confusion

Terminals and ATMs may offer to charge in the card's home currency instead of the local currency. This is called dynamic currency conversion, and the rate and any markup differ by provider. A statement can therefore show an amount that differs from what a shop displayed, which is not necessarily an error.

Good to know: Appears at terminals, ATMs and online checkouts.

Tip: The receipt shows which currency was chosen at the terminal.

8. Consumer Arbitration Committees and Courts – Public routes

If the issuer's reply does not settle the matter, the card law refers consumers to the arbitration committees and consumer courts under the Consumer Protection Law. Committees decide up to a value threshold set by regulation, and courts take other disputes. Deadlines and procedure are in the official texts, and the official text, not this guide, sets the current threshold.

Good to know: Located through the local trade administration and the courts.

Tip: A lawyer can say which route fits a particular case.

9. Fraud Reports and Advice – Criminal side

Fraud is a criminal offence, and reports go to the police or the public prosecutor's office. Issuers may ask for a report as part of a dispute. Insurance, the law and individual rights are questions for a licensed lawyer or adviser, and rules depend on nationality, residence status and date.

Good to know: Local police stations and prosecutor offices accept reports.

Tip: A report number can be quoted to the issuer and insurer.

Good to know

• Statements show the merchant's descriptor, and a quick look at the date and place often explains an unfamiliar item before any dispute.
• Duplicate charges can be pending authorisations that fall away, a point issuers explain in their own notes.
• Subscriptions and free trials appear on statements months later under the provider's name, which is a common source of unrecognised items.
• A card issued abroad follows the home issuer's dispute rules, and the deadline there may differ from the Turkish card law.
• Receipts, order confirmations and screenshots with dates form the usual evidence file.
• Figures for fees, thresholds and time limits exist only in official texts and contracts and change, so a number heard elsewhere may be outdated.

General information we collected from public sources, not financial, tax, investment or legal advice. We are not financial experts, tax advisers or lawyers. Rules, fees and offers change, so check with the provider or an authorised adviser.

FAQ

Who handles an unrecognised card payment?

The card issuer, meaning the bank that issued the card. For a card issued abroad this is the home bank, even if the payment took place in Turkey. The issuer's app or customer line is the first contact, and the issuer explains its dispute steps.

Is there a deadline to object to a card statement item?

Yes. The card law gives a limited window after the payment due date, and an item not disputed in time becomes final between cardholder and issuer, although court rights under general rules remain. The exact period is in the law and the issuer's terms.

Who proves a disputed online payment?

For card-not-present purchases by phone, online or order form, the card law puts the burden of proof on the merchant. For recording errors it falls on the issuer. Facts differ, so the issuer or a lawyer answers individual cases, and the contract matters too.

What is a chargeback?

It is a dispute procedure run between the issuer and the merchant's bank under card-network rules. Individuals do not start it themselves, since the issuer decides whether and how to use it. Rules, deadlines and results depend on the network and the facts.

Why does my statement show an amount different from the shop price?

Terminals and online checkouts may offer charging in the card's home currency, called dynamic currency conversion, with its own rate and markup, or the issuer may apply its own conversion. The receipt shows which currency was chosen. A difference is not necessarily an error.

Can a dispute go to a public body?

Yes. After the issuer's reply, consumer arbitration committees and consumer courts apply under the Consumer Protection Law, as the card law states. Committees decide up to a value threshold set by regulation that changes over time. Procedures and deadlines are in the official texts.

Does the card law cover lost or stolen cards?

It caps the cardholder's liability for unauthorised use, with exceptions for gross negligence or failure to report, and it requires issuers to arrange insurance for that capped liability. The law's text and the contract set the details, and cards issued abroad follow their own national rules.

Do sanctions rules matter for disputes?

They can affect which cards and providers a reader may use at all. The sanctions rules of the reader's own country may restrict Turkish banks and payment services, and readers check this with their own bank. This guide does not comment on such rules.
