To cancel a Direct Debit:
Go to your Direct Debits
Choose the Direct Debit you want to cancel
Select Cancel Direct Debit
Make sure to cancel at least 1 working day before your payment is due, otherwise the Direct Debit might still go through.
Cancelling a Direct Debit won’t cancel the contract or subscription you have with the company you were paying. So don’t forget to cancel with them, or give them different account details. If you don’t, you might still owe them money, and they might charge you an extra fee for not paying on time.
