Yes, you can dispute a charge, and your card issuer is legally required to investigate
When you spot a charge on your statement that you didn't make, didn't authorize, or believe is wrong, you have the right to dispute it. Your card issuer — the bank or company that issued your card — must look into your claim and either reverse the charge or explain why it stands. This protection exists because credit card transactions can go wrong in ways that are genuinely not your fault: a merchant might charge you twice, bill you for something you returned, or process a payment under a name so different you don't recognize it at first.
The process is called a chargeback or dispute, and it's separate from asking the merchant directly for a refund. You don't need the merchant's permission to start one, and you don't lose your right to dispute just because you gave your card number willingly. The card issuer's job is to sort out whether the charge was legitimate.
Key Takeaways
- Contact your card issuer as soon as you notice a charge you don't recognize — most have a 60-day window from the statement date, though reporting sooner protects you better.
- You'll need to explain what's wrong with the charge: you didn't make it, you cancelled the transaction, the merchant charged you twice, or the amount is incorrect.
- Your card issuer will likely issue a temporary credit while they investigate, so you're not out the money during the process.
- The merchant gets a chance to respond with evidence that the charge was valid, so gather your own proof (emails, receipts, cancellation confirmations) before you dispute.
- If the dispute is resolved in your favor, the charge stays reversed; if not, you can escalate to your state's banking regulator or file a complaint with the Consumer Financial Protection Bureau.
How to start a dispute with your card issuer
Call the customer service number on the back of your card or log into your online account and look for a "dispute" or "report a problem" option. You'll need to describe the charge clearly: the date, the merchant name, the amount, and exactly what went wrong. Be specific. "I don't recognize this" is a starting point, but "I returned this item on [date] and was never refunded" or "This merchant charged me twice for the same order" gives the issuer something concrete to investigate.
Most card issuers will ask you to file the dispute in writing — either through your online account, by mail, or by email. Some will let you start over the phone, but they'll follow up with a written confirmation you need to sign and return. Keep a copy of everything you send. The issuer will assign your dispute a reference number; write it down and use it in any follow-up contact.
What happens after you file a dispute
Your card issuer will usually place a temporary credit back on your account within a few business days — often before they've finished investigating. This is called a provisional credit, and it means you're not stuck without the money while the process unfolds. The credit is temporary because the merchant gets a chance to fight back.
The issuer sends the dispute to the merchant, who then has time (usually 7 to 10 business days, sometimes longer) to respond with evidence that the charge was valid. This might be a signed receipt, a delivery confirmation, an email exchange showing you authorized the charge, or proof that you received the goods or service. If the merchant doesn't respond or can't prove the charge was legitimate, the provisional credit becomes permanent and the dispute is closed in your favor.
The whole investigation typically takes 30 to 90 days. Your card issuer will contact you with the outcome. If they rule against you, they'll explain why — usually because the merchant provided proof you authorized the charge or received what you paid for.
Charges that are easier to dispute and win
Unauthorized charges — ones you genuinely didn't make — are the strongest disputes. If your card number was stolen or someone used your card without permission, the issuer has a clear duty to reverse it. Bring any evidence that your card was compromised: a police report if you reported fraud, a statement from your bank about suspicious activity, or proof that your card was physically lost or stolen.
Duplicate charges are also straightforward. If a merchant charged you twice for one purchase, show the issuer both charges on your statement. Charges for returned or cancelled items are winnable if you have proof of the return or cancellation — a return shipping label, a cancellation confirmation email, or a receipt showing the return was processed. Amount errors — the merchant charged $150 when the agreed price was $100 — are easy to dispute if you have documentation of what you were supposed to pay.
Charges you're less likely to win involve disputes over the quality of goods or services, or disagreements about whether a service was actually rendered. If you ordered a shirt, received it, wore it once, and now think it's poor quality, the merchant can argue you got what you paid for. If you hired someone to fix your roof and you're unhappy with the work, that's a contract dispute, not a billing error — and the card issuer usually won't reverse it.
Gather your evidence before you dispute
Before you contact your card issuer, collect anything that supports your side of the story. If the charge is unauthorized, gather proof of when and how you discovered it. If it's a duplicate, screenshot both charges. If you returned an item, find the return confirmation or tracking number showing it was delivered back to the merchant. If you cancelled a subscription, save the cancellation confirmation email.
If you've already contacted the merchant and they promised a refund, save those emails too — they show you tried to resolve it directly first. If the merchant ignored you or refused to help, that's also worth documenting. The card issuer doesn't require you to prove you contacted the merchant before disputing, but evidence that you tried and failed strengthens your case.
What happens if the dispute is resolved against you
If your card issuer decides the merchant's evidence is stronger than yours, they'll remove the provisional credit and the charge will stand. They'll send you a written explanation of their decision. At this point, you have options. You can request that the issuer reconsider if you have new evidence, though this rarely changes the outcome. You can file a complaint with your state's banking regulator or with the Consumer Financial Protection Bureau (CFPB) at consumerfinance.gov, though these agencies investigate whether the issuer followed the law, not whether the merchant was right.
If the dispute involves a significant amount of money or you believe the issuer made a clear error, you can also consult a lawyer, though the cost may not be worth it for smaller disputes. Some credit card issuers have additional dispute processes or escalation paths — ask customer service whether you can appeal to a supervisor or file a second-level dispute.
How disputes affect your credit and the merchant
Disputing a charge does not hurt your credit score. The dispute itself is not reported to credit bureaus, and it doesn't show up on your credit report. However, if the dispute is resolved against you and you don't pay the charge, then non-payment could eventually hurt your score — so don't ignore a charge just because you disputed it and lost.
For the merchant, a chargeback is costly and damaging. They lose the sale, pay a chargeback fee to the card issuer (often $15 to $100), and if they accumulate too many chargebacks, their payment processor may drop them. This is why merchants take disputes seriously and often respond quickly with evidence. It's also why some merchants are wary of high-risk transactions — they know a dispute is possible and they want to protect themselves.
Frequently Asked Questions
How long do I have to dispute a charge?
You have at least 60 days from the date the charge appeared on your statement to file a dispute. Some card issuers allow longer — check your cardholder agreement or ask customer service. The sooner you report it, the better, because the issuer can investigate while the transaction is still fresh and the merchant is more likely to have records.
What if I authorized the charge but the merchant never delivered what I paid for?
You can still dispute it. This falls under "services not rendered" or "merchandise not received." You'll need to show the issuer that you paid but didn't get the goods or service — an order confirmation, a tracking number that shows no delivery, or emails proving the merchant acknowledged they didn't complete the work. The merchant will have a chance to prove they did deliver, so have your evidence ready.
Can I dispute a charge if I'm just unhappy with my purchase?
Probably not. If you received the item or service you paid for, the merchant can argue the charge was valid even if you're dissatisfied. Your recourse is to ask the merchant for a refund under their return policy, not to dispute the charge. Disputes are for billing errors and unauthorized charges, not for buyer's remorse.
Will the merchant know who disputed their charge?
Yes. When you dispute a charge, the card issuer notifies the merchant and tells them your name and the reason for the dispute. The merchant then has a chance to respond. This is why some merchants contact customers directly when they receive a chargeback notice — they're trying to resolve it before the investigation concludes.
What if my card issuer sides with the merchant but I have new evidence?
Contact your card issuer and ask about their appeal or reconsideration process. Provide the new evidence in writing and explain why it changes the outcome. Some issuers will reopen a dispute if you present something they didn't see the first time, but this is not may provide. If the issuer won't budge, you can file a complaint with the Consumer Financial Protection Bureau, though they investigate the issuer's process, not the merchant's guilt.
