How to resolve a disputed credit card bill: A simple step-by-step process

Almost every disputed credit card bill starts with one thing: a charge you don't recognize, an incorrect amount, a duplicate entry, some merchant mistake, or pure fraud. Sometimes it will be a subscription auto-renewal that you had forgotten about, a failed payment charged to you anyway, or a refund not processed. Knowing what kind of error has occurred will further help you take the right course of action and communicate your case clearly with the bank.

The moment you notice something off, open your detailed transaction list in your banking app. Many banks show expanded details: date, time, merchant code, location, and even transaction type. A quick check often reveals whether it's a known merchant appearing under a different name or a delayed posting from a recent purchase. If the charge still looks wrong, make a note of the exact amount, date, and reference number. This becomes essential to raising the dispute later.

When the transaction involves a shop, restaurant, travel, booking, or online service, it is helpful to contact the merchant directly. Many disputes get resolved at this stage, as the merchant can immediately verify whether they processed the transaction or made an error. In most cases, when the merchant accepts the mistake, the charge is reversed within days. If they deny it, or if the number is unreachable, then you can move to the formal dispute stage.

Each credit card issuer has a built-in dispute option, either through the mobile app, phone banking, or a secure message. When you file the complaint, the bank temporarily begins an investigation. You may be asked to upload copies of bills, screenshots of conversations, an e-mail from the merchant, or a short written explanation. As soon as the dispute is logged, the bank issues an acknowledgement and gives you a reference number. Many banks also offer instantaneous provisional credit so that you do not have to bear the loss during the period of the investigation.

Depending on whether international payment networks like Visa or Mastercard have been used, a billing dispute investigation usually takes between 30 and 90 days, after which banks usually contact the merchant's bank for documents. In this case, if the merchant does not provide proof-such as a charge slip, invoice, or confirmation of delivery-the dispute is usually settled in the cardholder's favour. If valid proof is provided by the merchant, the bank reinstates the charge. Monitoring SMS and email alerts ensures you do not miss such updates.

If a charge has been disputed, it is best to continue paying the undisputed portion of the credit card bill. This would stop the interest from piling on the remaining balance. If the bank has given any provisional credit, that amount does not attract any interest as long as the dispute is going on. Banks always mention this in the dispute acknowledgement, so it's always safer to check the updated bill before making your payment.

This sometimes involves additional documents that the bank may require as proof, such as the service having been cancelled or evidence that the product was never delivered. The sooner a response is made, the quicker the investigation goes. If you miss out on these requests or respond later, the bank might close the dispute in favour of the merchant. Keeping all email confirmations, screenshots, and receipts in one place makes the process easier.

Once the investigation is complete, the bank sends a written explanation of the outcome in writing. If the dispute is resolved in your favour, then that provisional credit becomes permanent; otherwise, it could resurface in the next cycle. If you still disagree with the decision, then you can ask for a re-evaluation with more evidence. Some issuers also allow escalation to the card network or the internal grievance redressal officer.

Once the issue is resolved, it's a good idea to go through your card settings. You can disable international transactions, switch off contactless payment, block recurring auto-debits you don't use, or configure alerts for every swipe. Most individuals also revisit linked apps and subscriptions at this stage to see any silent charges in the background. Tokenised cards, two-factor authentication, and spending limits are fraud protection features that add a layer of security.

Most disputes are resolved easily if a step-by-step process is followed in an orderly manner. Once you get used to the different dispute tools your bank offers, managing and protecting your card payments will be much easier in the long term.
