Yes, you can dispute a charge, but the process and timeline depend on what happened
You can dispute a charge on your bank account, but the bank's responsibility to investigate depends on whether the charge was truly unauthorized or whether you authorized it but want to reverse it for other reasons. If someone used your card or account number without permission, that is an unauthorized transaction and the bank must investigate. If you authorized the charge but changed your mind, received defective goods, or were charged twice, you are asking for a chargeback — a different process with different protections.
The bank does not automatically refund you while investigating. You will likely see the charge stay on your account for 10 to 30 days while the bank gathers information from you and the merchant. Some banks offer provisional credit — a temporary refund while the dispute is open — but this is not may provide and depends on your bank's policy and the type of dispute.
Key Takeaways
- Unauthorized transactions (fraud) and authorized transactions you want reversed (chargebacks) follow different timelines and have different success rates.
- You must report an unauthorized charge within 60 days of receiving your statement, or the bank may not investigate.
- The bank has 10 business days to acknowledge your dispute and 45 days to complete the investigation, though the process often takes longer.
- Chargebacks for authorized transactions you regret — wrong item, changed your mind, merchant error — succeed only if the merchant refuses to refund you or if you can prove the charge was not as described.
- The merchant can fight back and provide evidence that you authorized the charge, which may result in the charge being reinstated even after the bank initially refunds you.
Unauthorized transactions versus chargebacks: which one you have
An unauthorized transaction is a charge made without your permission — someone stole your card number, your account credentials, or your physical card and used it. The bank's fraud department handles this. You report it, the bank investigates, and if they confirm it was fraud, they refund you and typically close the compromised account or reissue your card.
A chargeback is a dispute over a charge you did authorize. You ordered something and it never arrived. The merchant charged you twice by mistake. The item arrived damaged or was not what you ordered. You changed your mind and the merchant will not refund you. In these cases, you are asking the bank to reverse a legitimate transaction on your behalf. The merchant gets a chance to defend the charge, and the outcome is less certain.
The distinction matters because banks treat fraud more seriously — they have a legal obligation to investigate unauthorized transactions under federal law. Chargebacks are more discretionary and depend partly on the merchant's response and your ability to prove your claim.
How to report an unauthorized charge to your bank
Contact your bank when ready by phone, not email. Call the number on the back of your card or on your bank statement. Have your account number, the disputed charge amount, and the date of the charge ready. Tell the bank representative that the charge is unauthorized and you did not make it.
The bank will ask you questions: Do you recognize the merchant? Did anyone else have access to your card? Have you noticed other unauthorized charges? Answer honestly. The bank is building a record of your claim. Ask the representative to document the call and confirm the dispute reference number before you hang up.
Follow up in writing. Send a letter to the address on your statement marked "Dispute Notice" or "Fraud Report." Include your account number, the charge amount, the date, the merchant name, and a brief statement that you did not authorize it. Keep a copy. This creates a paper trail and ensures your dispute is formally logged.
Do not use the merchant's refund process for fraud. If someone stole your card, contacting the merchant directly wastes time. The bank needs to investigate the fraud itself, not negotiate with the merchant.
The bank's investigation timeline and what happens to your money
The bank must acknowledge your dispute within 10 business days. This does not mean they have resolved it — it means they have received it and opened an investigation file. You will receive a letter or email with a dispute reference number.
The investigation itself takes up to 45 days. During this time, the bank contacts the merchant, requests transaction records, and reviews your account activity. They may ask you for additional information — a copy of your ID, proof that you reported the fraud, or details about when you discovered the unauthorized charge.
Your money during the investigation: The charge typically remains on your account and counts against your available balance. Some banks offer provisional credit — they refund you temporarily while they investigate — but this is voluntary and varies by bank. If the bank grants provisional credit, the money appears in your account within a few days, but it is not final. If the investigation concludes the charge was authorized, the bank will reverse the provisional credit and you owe the money again.
The investigation conclusion comes in writing. If the bank finds the charge was unauthorized, they remove it permanently and you keep any provisional credit. If they find the charge was authorized or cannot determine otherwise, they close the dispute and the charge stays on your account.
Disputing a charge you authorized but want reversed
If you authorized the charge but the merchant did not deliver, delivered the wrong item, or charged you twice, you are initiating a chargeback. The process is similar — you contact the bank and explain the problem — but the outcome is less certain because the merchant can defend the charge.
Start with the merchant first. Email or call and ask for a refund. Explain what went wrong: the item never arrived, it arrived damaged, it was not what you ordered, or you were charged twice. Keep records of this communication. If the merchant refuses or does not respond within a reasonable time (usually 7 to 10 days), then contact your bank.
When you call the bank, explain that you authorized the charge but the merchant has not resolved the problem. Provide the merchant's name, the charge date, the amount, and a summary of what went wrong. The bank will open a chargeback dispute. This is where the merchant gets involved: the bank notifies them that you are disputing the charge and gives them a important date — usually 7 to 10 days — to respond with evidence that the charge was legitimate.
The merchant can provide proof: a delivery confirmation showing the item arrived, a signed receipt, email correspondence showing you agreed to the charge, or a refund they already issued. If the merchant provides strong evidence, the bank may side with them and the charge stays on your account. If the merchant does not respond or their evidence is weak, the bank refunds you.
What to do if the bank denies your dispute
If the bank closes the dispute in the merchant's favor, you have options. First, check the bank's decision letter for the reason. Common reasons: the merchant provided proof you authorized the charge, the dispute was filed too late, or the bank could not verify your claim.
If you believe the bank made an error, you can request a supervisor review. Call the bank's dispute department and ask to escalate the case. Provide any new evidence: emails from the merchant, photos of a damaged item, proof of a refund the merchant promised but did not send. The supervisor will review the file again, but the outcome is often the same.
If the dispute involves a credit card, you have additional protection: you can file a complaint with the Consumer Financial Protection Bureau (CFPB) if you believe the bank did not investigate fairly. The CFPB cannot overturn the bank's decision, but they can investigate whether the bank followed the law. For debit card disputes, your protections are weaker, which is one reason many people prefer credit cards for online purchases.
How to protect your account after a dispute
If the dispute was fraud, the bank will typically reissue your card with a new number. Do not use the old card again. Update any subscriptions or recurring charges to the new card number to avoid declined payments.
Monitor your account for the next 30 to 60 days. Fraudsters who have your information often make multiple small charges to test whether the account is still active. Check your statement weekly. If you see more unauthorized charges, report them when ready — each one restarts the investigation clock, but reporting them quickly strengthens your case.
Consider placing a fraud alert or credit freeze with the three credit bureaus (Equifax, Experian, TransUnion) if the fraud involved your Social Security number or if you suspect identity theft. A fraud alert tells lenders to verify your identity before opening new accounts. A credit freeze prevents anyone from opening accounts in your name without your permission. Both are free.
Frequently Asked Questions
How long do I have to report an unauthorized charge?
You must report it within 60 days of the date the charge appears on your statement. If you miss this important date, the bank may refuse to investigate and you lose federal fraud protections. Some banks have shorter windows, so check your account agreement.
Will I get my money back while the bank investigates?
Not automatically. The charge stays on your account and counts against your balance. Some banks offer provisional credit within a few days, but this is temporary and reversed if the investigation finds the charge was authorized. Ask your bank about their provisional credit policy when you file the dispute.
What if the merchant says I authorized the charge and I disagree?
The bank will ask for evidence from both sides. If you have emails, receipts, or other proof that you did not authorize it, provide them. If the merchant has proof you did authorize it, the bank will likely side with them. This is why chargebacks for authorized transactions are harder to win than fraud disputes.
Can the merchant charge me again after the bank refunds me?
If the bank refunds you and the merchant later provides evidence that the charge was legitimate, the bank may reverse the refund and reinstate the charge. You will owe the money again. This is why the dispute process takes time — both sides get a chance to present evidence.
What is the difference between a dispute and a chargeback?
A dispute is the formal process you start with your bank. A chargeback is what happens when the bank reverses the charge on the merchant's account. You file a dispute; the bank processes a chargeback. The terms are often used interchangeably, but technically a chargeback is the outcome of a successful dispute.
