Cancelling a Direct Debit
You can cancel Direct Debits in the app:
Tap the Payments icon in the menu bar
Tap the payment you want to cancel
Tap Cancel Direct Debit
Bear in mind that you’ll need to cancel a Direct Debit at least one full day before it’s due to leave your account, otherwise it might still go through.
If the company's tried to take this payment before and failed, there’s a chance this can still be taken as a recollection payment if they think you owe them money. Don’t forget to let the company know that you’ve cancelled, too.
