If there is a charge on your credit card statement that you do not recognize, notify CIBC within 30 days of the statement period shown on the front of your monthly statement where the transaction first appears. Call CIBC Credit Card Services at 1-800-465-4653 (Canada & U.S.) or 514-861-4653 (elsewhere; collect calls accepted) as soon as possible with the transaction details, including the transaction date, description of the transaction and the date of the statement.
To speak with a Customer Service Representative regarding your dispute, follow the steps below on a phone:
- Select your language from the first menu
- Input your CIBC credit card number and press the number sign (#)
- Select option 3 (for disputes)
After your call, CIBC may request a copy of the transaction receipt from the merchant. If necessary, a copy will be mailed to you, along with a letter confirming your request. Please allow up to 45 days to receive this. If, after reviewing the transaction receipt, you determine that the charge is not valid, simply sign the letter and return it to CIBC (detailed instructions will be included in the body of the letter). Depending on the information provided in your response and how quickly you respond, we will pursue an investigation and initiate a dispute on your behalf.
Please note that CIBC does not deal directly with merchants. Customer disputes are handled with the merchant's financial institution.
