Direct Debits
If you have a direct debit set up for your monthly payments, you can cancel that via the mobile app or through Online Banking. You can still make one off payments every month to ensure you pay at least your minimum monthly payment.
Paying your minimum monthly payment can help you reduce your costs in the short term, however it means that it would take longer to pay off your credit card debt. If you are able to pay more than the minimum monthly payment you could clear your balance sooner and prevent interest from building up.
