Credits From Returned Purchases. If you return a Purchase that you made with your Card and the merchant issues you a credit, we will credit the Card Account for that amount. Credits will only affect the daily interest-bearing balance if the transaction was posted to the Card Account. So if we don’t receive the credit before we add the related Charge to the Statement, the Primary Cardholder must make the payment based on the balance shown on the Statement, even if the balance is higher than you expected it to be because a credit is expected. If we charge interest on the Card Account because of a transaction that we later receive a credit for, we will not refund the interest charged. Even though we don’t have to, if we credit the Card Account, all of your rights and claims related to the credit are automatically assigned (legally transferred) to us. You agree to sign any documents we ask you to that relate to this assignment.
