What happens if I fail to make a Q PLAN repayment?

If you fail to make a Q PLAN repayment, then that amount will be overdue; it will not form part of the Q PLAN or Q PLAN Remaining Balance; instead will become part of the Closing Balance of your Account and interest will be calculated and debited to your Account on that overdue amount at the Expired Promotional Rate applying to your Account, from the time it becomes overdue until it is paid in accordance with the Cardholder Terms and Conditions applying to your Account.
