I called in to the call centre to change my debit order details(month in advance) only to havw them debitthe old account again. Then i called in 2nd time to correct the account and AGAIN the debit the wrobg account. By this time they have suspended my account.after my 3rd call Patience tell me it will take another week as they can only instate a debit order wednesday after long weekend because there is no one that can assist now. So i have to sit with a suspended account For over a week because of their error. What type of poor service is that. No one can help me. I will def be closing me account with them.
