How do I stop or cancel a direct debit ?
You may cancel a direct debit at any time by notifying us on 13 25 85 or visiting one of our branches. We would encourage you to notify the debiting institution of your request to cancel the direct debit.
The cancellation of direct debit received on the same day a direct debit is scheduled will not take effect until the next business day.
Once notified of the cancellation, we can stop any further payments from being made.
