If you do not pay the Total Payment Due Including Instalment(s) amount by your Payment Due Date, your Instalment Plan(s) will be cancelled.   You can check your Total Payment Due Including Instalment(s) amount on your account statement.   Upon cancellation, the outstanding balance will revert to your standard interest rate for purchases which is higher than the Instalment Plan rate.  Interest will then accrue in the usual way until the total amount is paid off.   WARNING: Once an Instalment Plan is ended it cannot be reinstated.
