RUN AROUND ON CANCELLATION / CLOSURE OF ACCOUNT

I paid off my credit card, sent an email to Absa Bank Credit Card Division to please cancel the credit card. They advised I needed to pay an additional amount which was the interest. I paid that. Resent the email cancell the card. As I am overseas I have tried to call ABSA where I have a recording of one department to another. No joy in speaking to anyone about the card. I want this card cancelled. You accepted my payment but are giving me the run around about closing this account. I will not pay another amount to ABSA Bank. I HAVE INSTRUCTED YOU TO CANCELL THE THING!!!! I DONT WANT IT!!! THE NEXT MOVE WILL BE REPORTING YOU TO THE DEBT COUNCIL OF SOUTH AFRICA WHERE YOU ARE FORCING ME TO KEEP A CARD I DO NOT WANT!!! NOW CANCEL THE THING!!!
