Transactions that appear on your account may be disputed with the bank within 30 days.
The procedure to process a dispute is as follows:
1. Call the merchant directly. Most merchants would prefer to resolve the problems themselves and are willing to provide credits.
2. If a charge is not recognized by the cardholder and the merchant is not willing to resolve the problem, the cardholder should call JPMorgan Chase Customer Service promptly. In addition, submit a Dispute Form located on Smart Date On-Line (SDOL), print and fax or mail the dispute form to the bank.
