A family member recently cancelled a preauthorized credit card payment [auto-pay] around July 9, 2024.

The current bill states that the amount will still be automatically deducted on July 27, 2024. However, Shaw's terms and conditions specify that changes may take one full billing cycle to reflect in the system.

When I called on July 16, 2024, a Shaw representative assured me that  manually make a payment on July 27, 2024 will be necessary and there will not be a double payment (where Shaw automatically deducts the payment from the account).

This seems to contradict your policy.
