Debit orders

I have moved to Scotland, and have now paid all my outstanding accounts with Fnb on the 18.03.2016<br> <br> On the 25.02.2016 they debited my account with the amount of R593.48 for a credit card payment which is not mine, then on the 02.03.2016 they debited R454 for another credit card payment, but I do not have two credit cards with them.<br> I called online banking and they transferred me to different departments then I was put on hold for almost 20min which costs me about R230 I had to hang up. I just made a payment of R8591.48 to pay off my credit card on the 18.03.2016, when I checked my account today they have debited once again R454 and I still have an outstanding balance on my credit card of R454 why is that if I have paid the account up in full.<br> <br> Can someone please call me to explain this I can not keep calling the call center because no one seems to know what they are doing.
