If a purchase you’ve selected for a U.S. Bank ExtendPay® Plan is refunded by the merchant, the returned amount will be credited to your current credit card account balance.
Since the refund won’t specifically be applied to the U.S. Bank ExtendPay® Plan, your ExtendPay® balance and monthly minimum payment will not change unless your current balance is paid in full, including any activity on your credit card account since the previous statement.
