Mistakes in the amount billed and duplicate charges should be resolved directly with the merchant.
If you are unable to resolve a dispute with a merchant, you must report it within 60 days to US Bank Customer Service Office at 800-344-5696. In addition to contacting the bank, you must also complete the Dispute Reporting Form.
U.S. Bank will investigate and credit the amount of the disputed charge back to the account once the investigation is completed, normally within 30 days. If the resolution is in favor of the merchant, the account will continue to be charged for the disputed amount at the end of the investigation.
Failure to report a dispute within 60 days of the statement date will result in the department absorbing the expense.
