A charge you don’t recognize on your credit card statement is one of the most expensive ordinary problems. It’s small enough that most people put it off, and it gets more expensive the longer it sits, because interest on that balance compounds while you wait for someone to pick up the phone.
The frustrating part is that federal law gives you real rights: deadlines, mandatory investigation timelines, provisional credit you can’t be refused. Almost nobody uses them, because the protections live in the fine print of a disclosure nobody reads, and because most cardholders do the one thing that quietly destroys their claim. They wait.
There are two different disputes, and mixing them up is why claims die
An unauthorized transaction is one you didn’t make and didn’t authorize: your card was cloned, your number stolen, or someone ran charges against an account you didn’t open. You have up to two years after the first statement following the transaction to report it, and liability is capped at $50 in the situations where a cap applies.
A billing error covers nearly everything else, and it’s the bigger category by far. The federal definition includes a charge you didn’t authorize, a charge for an amount different from what you agreed to, duplicate charges, goods or services not delivered as promised, and a credit or return never applied to your account. You have 60 days from the date your statement was sent.
Here’s the trap. If you book a hotel room, stay in it, and the hotel then bills you a damage fee you never caused, you authorized that transaction. Writing “fraud” or “unauthorized” on the dispute form points the issuer’s system at a stolen-card investigation, which asks whether you used the card. You did. Claim denied, and often fast. The same charge, described as a billing error because it was billed for an amount other than what you agreed to, is a legitimate claim the issuer must investigate. The facts didn’t change. The label did.
The deadline runs from your statement, not from the charge
The 60-day clock starts when the statement containing the charge was mailed or transmitted. It does not start when the transaction posted, and it does not restart when you notice it. Most think they have 60 days from the day they spotted it. Some have considerably less.
If no itemized statement was sent, the window is 60 days from when it should have been sent. Miss the billing-error deadline and the issuer’s obligation to investigate simply evaporates, not because they proved you wrong but because you let the clock run out. State law sometimes allows longer than the federal floor, but 60 days is the baseline you should never plan around.
Unauthorized transaction claims survive much longer: you can report one up to two years after the first statement that followed it. If a card was genuinely stolen and used, you have real time. If a merchant billed you wrong for something you did buy, you don’t.
What the issuer legally owes you once it has the claim
These are requirements, not courtesies:
- An acknowledgment within 30 days of receiving your dispute, telling you the date they received it. Save that letter — every downstream deadline is measured from the date on it.
- Resolution within two billing cycles or 90 days, whichever is shorter.
- Provisional credit at the 60-day mark. If they still haven’t resolved it 60 days after receiving your dispute, they must credit the disputed amount plus the interest on it. This is mandatory, and most cardholders don’t know it exists.
- For unauthorized charges, provisional credit within 10 business days, with up to 45 days to finish the investigation. If they can’t finish, the credit stands permanently.
In practice, a correctly filed dispute is very likely to put your money back temporarily, long before anyone decides whose fault the charge was. The provisional credit is a bridge, not a verdict.
The four mistakes that get claims denied
- Waiting past the deadline. By far the most common, and the least recoverable.
- Leaving it on the phone. Calling is often the fastest way to file, but it’s the worst place to leave the record. Get a confirmation number, then follow up in writing through the issuer’s portal with the amount, date, merchant name, and exactly what you’re claiming.
- Being vague. “I don’t recognize this” is thin. “A $240 charge dated March 4 with a descriptor I can’t match to any receipt” is something an investigator can work with. Specificity costs nothing.
- Paying the disputed amount. Paying doesn’t automatically forfeit a billing-error claim, but it removes the leverage the provisional-credit deadline depends on. Ask about the dispute process first.
Build the file before you call
Most “unrecognized” charges turn out to be a legitimate merchant with an unreadable descriptor. Payment processors route transactions through names you’d never guess: “SQ *BLUE BOTTLE 0412” or an eighteen-digit string is often a coffee shop or a parking garage. Two moves identify it fast. Your issuer’s app or chat line will usually name the underlying merchant, and the phone number printed next to the descriptor usually identifies it from your side.
Keep the receipt, the cancellation email, the screenshot showing you cancelled before the charge hit, and any correspondence with the merchant. If services were never delivered, write to the merchant and the issuer at the same time rather than one after the other. Merchants and card networks run chargeback deadlines shorter than 60 days, and travel and event merchants in particular will refuse a late claim.
If the issuer says no
Read the denial letter. It has to tell you why, and it has to identify the law or the provision you can rely on. Vague denials are common and worth challenging.
Then escalate in this order: the issuer’s executive or ombudsman process, in writing and specific; a complaint to the Consumer Financial Protection Bureau, which is free, online, and forwarded to the company with a required response; then your state attorney general. Cardholder arbitration exists under most major issuers’ agreements, but the filing fee alone usually exceeds what you’d recover.
What not to do in the first hour
Don’t close the account. Closing a card strips away your dispute tools, hurts your credit history, and cuts off your leverage — and it doesn’t stop fraud. Lock the card number in your issuer’s app instead. And don’t argue with the first person you reach: front-line representatives have almost no authority to issue credit. Their job is to document and route. Your leverage is the letter that arrives after you file formally, and the deadlines behind it.
The order that works: lock the card, identify the merchant, file in writing inside 60 days of the statement, get the acknowledgment letter, then let the clock do its work. Most people lose these disputes because they waited, not because they lost.
