Stop a recurring charge
To stop a standard recurring charge, you change the end date for the charge. After you change the end date, Smile reviews the existing recurring charges and issues any necessary adjustments.
Warning: If you stop a recurring charge, Smile permanently removes the
charge from consideration when it processes the billing run. No new charges or
refunds are raised after you cancel the charge. Smile does not delete or refund any
charges that were already raised against the subscription.
CAUTION:
If you alter a recurring charge, you need to set an end date on the
existing charge before you add a new charge at the different rate, otherwise all
periods in the past will re-rate at the new rate.
This task explains how to stop a recurring charge.
