You can dispute a charge by contacting your card issuer, not the merchant

When you see a charge you don't recognize or believe is wrong, your card issuer — the bank or company that issued your card — is the one who investigates it, not the store or business that charged you. You start a dispute by calling the customer service number on the back of your card or logging into your online account. The issuer will then contact the merchant on your behalf and either reverse the charge, adjust it, or explain why it's valid.

The reason this matters: disputing through your card issuer gives you legal protection under federal law. If you pay the merchant directly or let them convince you the charge was correct without investigation, you lose that protection. Even if you think the merchant will fix it quickly, starting a formal dispute creates a paper trail and holds both sides accountable.

Key Takeaways

  • Contact your card issuer by phone or through your online account to start a dispute; do not contact the merchant first unless you want to try resolving it informally.
  • You have up to 60 days from the date the charge appeared on your statement to file a dispute under federal law.
  • The issuer will investigate and typically reach a decision within 30 to 90 days, during which the disputed amount may be temporarily removed from your balance.
  • Keep records of everything: the original transaction, your dispute claim, all emails and letters, and any proof that the charge was wrong.
  • If the issuer rules against you, you can request a second review, but the merchant's documentation usually determines the outcome.

The difference between a chargeback and a dispute

A dispute is what you file with your card issuer when you believe a charge is incorrect. A chargeback is what happens if the issuer agrees with you and reverses the charge. You don't request a chargeback directly — the issuer initiates it after investigating your dispute.

When a chargeback is issued, the merchant's bank is notified and the money is pulled back from the merchant's account. The merchant then has the chance to fight the chargeback by submitting evidence that the charge was legitimate. This is why disputes can take weeks or months to resolve: both sides get to present their case.

What counts as a valid reason to dispute a charge

The most common reasons are: you were charged twice for the same purchase, the amount charged was different from what you agreed to, you cancelled a subscription but were still charged, the item never arrived, the item arrived damaged or not as described, or you don't recognize the charge at all (which may indicate fraud or identity theft).

Less common but valid reasons include: the merchant promised a refund and didn't issue one, you returned an item but the refund never posted, or you were charged after cancelling a service. The key is that you have a legitimate reason to believe the charge is wrong — not just that you changed your mind about the purchase.

What does not count: buyer's remorse alone, a price drop after you bought, or a dispute over the quality of a service you received as promised. If you ordered something, received it in good condition, and simply didn't like it, that's a return or refund issue with the merchant, not a card dispute.

The step-by-step process for filing a dispute

Step 1: Gather your evidence. Find the transaction on your statement. Write down the date, amount, merchant name, and what you purchased. Collect any proof: order confirmation emails, tracking numbers, photos of damaged items, cancellation confirmations, or screenshots of the charge appearing twice. If you don't recognize the charge, note that too.

Step 2: Contact your card issuer. Call the number on the back of your card or log into your online account and look for a "dispute" or "report a problem" option. Some issuers have a dedicated fraud or disputes department; others handle it through general customer service. Have your statement and evidence ready when you call.

Step 3: Explain what happened. Tell the issuer exactly what's wrong with the charge. Be specific: "I was charged $89.99 on March 15 for a return I mailed on March 10" is better than "this charge is wrong." If you don't recognize the charge, say so clearly — the issuer may flag it as potential fraud.

Step 4: Submit written documentation. The issuer will likely ask you to put your dispute in writing. They may provide a form or ask you to send an email or letter. Include your account number, the transaction date and amount, the merchant name, and a brief explanation. Attach copies of your evidence (not originals). Keep a copy for yourself.

Step 5: Wait for the investigation. The issuer typically has 30 days to investigate but may take up to 90 days. During this time, the disputed amount may be temporarily removed from your balance, though you're not may provide a refund until the investigation closes. The issuer will contact the merchant and request proof that the charge was valid.

Step 6: Receive the decision. The issuer will notify you in writing whether the dispute was upheld (the charge is reversed), denied (you owe the money), or partially resolved. If upheld, the money is returned to your account. If denied, the charge stays and you can request a second review if you have new evidence.

What happens to your account during a dispute

While a dispute is open, the charge usually remains on your statement but may be marked as "disputed" or "under investigation." Some issuers temporarily credit the amount back to your account, but this is not may provide — it depends on the issuer's policy and the type of dispute.

Your credit score is not affected by filing a dispute. The dispute itself doesn't show up on your credit report. However, if the issuer rules against you and you don't pay the charge, that unpaid balance could eventually be reported as delinquent, which would hurt your score.

If the merchant files a chargeback dispute against you (claiming you're wrong), they may contact you directly to resolve it before the investigation closes. You can negotiate a refund or partial refund at this point, but do so in writing so there's a record.

How long a dispute takes and what to expect

Federal law requires issuers to acknowledge your dispute within 30 days and reach a decision within 60 days, though many take the full 90 days allowed. During this time, you may see the charge drop off your balance temporarily, reappear, or stay marked as disputed — the experience varies by issuer.

The merchant will be notified of your dispute and given time to respond with evidence. If they provide a signed receipt, delivery confirmation, or other proof that the charge was legitimate, the issuer is likely to rule in their favor. If they don't respond or can't provide proof, you're more likely to win.

After the issuer makes a decision, you'll receive written notice. If you disagree, you can request a second review, but you'll need to submit new evidence or information the issuer didn't see the first time. Simply disagreeing with the decision is not enough to reopen the case.

When to dispute versus when to contact the merchant first

If you recognize the merchant and believe it's a simple mistake — a duplicate charge, a wrong amount, or a promised refund that didn't post — you can try contacting them first. Many issues are resolved faster this way, especially if the merchant is responsive. Ask them to issue a refund and get confirmation in writing or email.

File a dispute immediately if: you don't recognize the charge at all (it may be fraud), the merchant is unresponsive, the merchant refuses to refund you, or you've already tried contacting them without success. You can also file a dispute even if you're trying to resolve it with the merchant — the two aren't mutually exclusive, though most people try one first.

If you suspect fraud or identity theft, file a dispute right away and also contact your issuer's fraud department. They may freeze your account, issue a new card, and monitor for other unauthorized charges. Don't wait to see if the merchant responds.

Frequently Asked Questions

What if I already paid the merchant to fix the charge?

You can still file a dispute for the original charge. Explain in your dispute claim that you paid the merchant separately to resolve it. The issuer will investigate the original charge; if they rule in your favor, you'll be refunded and can then seek reimbursement from the merchant for the payment you made.

Can I dispute a charge if I signed a receipt?

Yes. A signature doesn't prevent you from disputing a charge if the amount was wrong, the item didn't arrive, or the merchant broke an agreement. The signature proves you authorized a transaction, but not that the transaction was completed correctly or as promised.

What happens if the merchant wins the dispute?

The charge stays on your account and you owe it. You can request a second review if you have new evidence, but if the merchant provided proof of delivery or a signed receipt, a second review is unlikely to change the outcome. At that point, your options are to pay the charge or contact the merchant about a refund.

Do I have to pay the disputed charge while the investigation is happening?

No. If the issuer temporarily credits the amount back to your account, you don't owe it during the investigation. If the charge stays on your balance, you're still not required to pay it while the dispute is open — but if the issuer rules against you, the charge becomes due immediately.

Can I dispute a charge on a debit card the same way?

The process is similar, but debit card disputes have less legal protection than credit card disputes. You have fewer days to report it (usually 60 days, but some banks allow less), and the investigation may take longer. Contact your bank immediately if you notice an unauthorized debit card charge.
