How to start a dispute with Citibank
Citibank handles disputes through its Resolution Center, which you access through your online account or mobile app. You do not call a general customer service line and hope to reach the right department — you log in, find the transaction you want to dispute, and file directly. Citibank then assigns your case a reference number and tells you what happens next.
The fastest way is through your online account: log in, go to the transaction history for the account in question, find the charge you want to dispute, and select "Report as Disputed" or "Dispute This Transaction." The app works the same way. If you cannot access your account online, you can call the number on the back of your card and ask to file a dispute by phone, but having your statement and the transaction details in front of you makes the process faster.
You will need to describe what went wrong — whether the charge was unauthorized, the merchant charged you twice, the amount was wrong, or you never received what you paid for. Be specific about the date, amount, and merchant name. Citibank will ask you to confirm that you did not authorize the charge or that you have already tried to resolve it with the merchant.
Key Takeaways

- If you disagree with Citibank's decision, you can request that they reconsider or file a complaint with the Consumer Financial Protection Bureau.
What documents Citibank will ask for
The documents you need depend on the type of dispute. For an unauthorized charge, Citibank will ask you to confirm that you did not make the purchase and did not authorize anyone else to make it. For a billing error — a duplicate charge, wrong amount, or charge posted to the wrong account — you will need your statement showing the error.
For a "merchandise not received" dispute, Citibank will ask for proof that you placed the order and that the item never arrived. This might be an order confirmation email, a tracking number showing the package was not delivered, or a message from the merchant saying the item is out of stock. If you ordered from a third-party seller on a marketplace, keep screenshots of the listing and your order.
For a dispute about the quality of goods or services — you received something damaged or not as described — Citibank's process is different and usually slower, because the bank has to determine whether the merchant's description matched what you received. Photos of the damage or the item itself are helpful, as is any written communication with the merchant about the problem.
The timeline for a Citibank dispute investigation
Citibank must acknowledge your dispute within one business day and begin investigating within 30 days. During this time, the bank may ask you for more information. Respond as quickly as you can — delays on your end can extend the timeline.
The full investigation takes 30 to 90 days from the date you file. Citibank will contact the merchant and ask them to respond to your claim. If the merchant does not respond or their response does not resolve the issue, Citibank will rule in your favor. If the merchant provides evidence that the charge was legitimate — a delivery confirmation, a signed receipt, or proof of authorization — Citibank may rule against you.
You will receive the outcome in writing, either by mail or through your online account. If Citibank issued a temporary credit while investigating and then rules against you, they will remove that credit from your account. This is why it is important to keep your own records of the dispute and not assume the temporary credit is permanent.
Temporary credits and what happens if you lose
Citibank may issue a temporary credit to your account while the investigation is ongoing. This credit is not final — it is a courtesy to keep you from being out the money while the bank investigates. If Citibank later determines that the charge was legitimate, they will reverse the temporary credit and you will owe the amount again.
If you lose the dispute, you have options. You can request that Citibank reconsider if you have new evidence — for example, if the merchant later admits the charge was wrong, or if you find proof that you returned an item. You can also file a complaint with the Consumer Financial Protection Bureau (CFPB) if you believe Citibank did not investigate fairly or did not follow the rules for dispute handling.
To file a CFPB complaint, go to consumerfinance.gov and use their complaint portal. You will describe what happened, what Citibank decided, and why you think the decision was wrong. The CFPB will forward your complaint to Citibank, and Citibank has 15 days to respond. The CFPB does not make a final decision, but their involvement sometimes prompts banks to reconsider.
Disputes for debit cards versus credit cards
The process is the same whether you are disputing a Citibank credit card or debit card charge, but the legal protections are different. Credit card disputes are covered under the Fair Credit Billing Act, which limits your liability to $50 if someone uses your card without permission. Debit card disputes fall under the Electronic Funds Transfer Act, which limits your liability to $50 if you report the fraud within two business days, but up to $500 if you wait longer.
This means if your debit card is stolen and used, you should report it to Citibank when ready — the same day if possible. For credit cards, the 60-day window to dispute is more forgiving because your liability is capped at $50 regardless of how quickly you report. Either way, file your dispute as soon as you notice the charge.
What to do if the merchant is unresponsive
If you have already contacted the merchant and they are not responding or refusing to help, that is when you file a dispute with Citibank. Do not skip the merchant step — Citibank will ask whether you tried to resolve it directly first. If you have emails or messages showing you contacted the merchant, save those and mention them when you file your dispute.
Some merchants are slow to respond to Citibank's investigation requests, which can delay the outcome. If weeks pass and you have not heard from Citibank, call the number on the back of your card and ask for an update using your dispute reference number. Citibank can tell you whether they are still waiting for the merchant to respond or whether they need something from you.
Preventing disputes in the first place
The easiest dispute to handle is one you never have to file. Before you make a purchase, especially online or from an unfamiliar merchant, check the return policy and make sure you understand what you are buying. For large purchases, use a credit card rather than a debit card — the fraud protections are stronger.
Keep your receipts and order confirmations, and monitor your statements regularly. Many people catch unauthorized charges weeks after they happen because they do not look at their statements. Set up account alerts through your Citibank app so you are notified of large charges or charges from certain merchants. If you see something you do not recognize, dispute it right away rather than waiting to see if it resolves itself.
Frequently Asked Questions
How long do I have to dispute a charge with Citibank?
You have 60 days from the date the charge appears on your statement. After 60 days, Citibank cannot open a dispute for you. If you are close to that important date, file when ready through the Resolution Center rather than waiting to gather more information.
Will I get my money back while Citibank investigates?
Citibank may issue a temporary credit while they investigate, but this is not may provide. If they do issue a credit and later rule against you, the credit will be removed. Do not count on the temporary credit as permanent until the investigation is complete.
What if Citibank sides with the merchant?
You can ask Citibank to reconsider if you have new evidence. You can also file a complaint with the Consumer Financial Protection Bureau at consumerfinance.gov. The CFPB will review whether Citibank followed the correct process, though they cannot override Citibank's decision.
Can I dispute a charge if I authorized it but changed my mind?
No. A dispute is for unauthorized charges, billing errors, or merchandise that was not received or was not as described. If you authorized the charge but straightforward changed your mind about the purchase, you need to contact the merchant about a return or refund instead.
Do I have to pay the disputed amount while the investigation is happening?
No. You do not have to pay a disputed amount while Citibank investigates. If they issue a temporary credit, that amount is not due. If they do not issue a temporary credit, you still do not have to pay until the investigation concludes.
