Totally pathetic ! Cant get it right!

I have had a VERY frustrating experience with ABSA credit Card Division. I had an ABSA credit card and closed the account in 2012. I have since been receiving credit card statements which i could not open. I ignored these emails as i was under the impression that the consultant closed the account as i requested in 2012. A few months ago i called the card division and was told my account was still open , i then spoke to the manager who informed me that there was an outstanding amount of money on the account and they cant close it. This made NO sense to me as i had paid the amount that the consultant in 2012 had confirmed to me and nobody from ABSA has EVER called me to inform me of the outstanding amount. The manager assured me that she will close the account and i refused to pay the money as i dont feel this is my faul and she said that she would write the money off. I dont even have the card or account details . To my horror i am STILL receiving statements which can only mean that the account is STILL open!!! CAN SOMEONE DO THEIR JOB AND CLOSE THE DAMN ACCOUNT! i will NOT be paying ANY outstanding money as this is the 3rd time i have asked for this ACCOUNT TO BE CLOSED!
