What does ABSA want from Me?

My Name is Bongani Dhlamini, I opened up my ABSA credit card in January 2015 and the real reason for this complaint is that on the 25/11/2015 I called the credit card department asked for a settlement figure to close off the account the lady who assisted me was Tsholofelo she asked me why I told her because of bad service she told me that she was sorry on behalf of the bank and my settlement amount was R12, 178.54 the same day I went to my bank here in Rosebank to withdraw the same amount and went straight to ABSA in Rosebank to settle it after paying off ABSA I called them to close off the account and I spoke to some guy who confirmed to me that my account was in order and settled, he said I can now tear off the card I asked for a settlement letter he said that it was on the way. I was happy but my happiness was cut short when the following day I received an email from ABSA saying that I owe them R124.95 with all due respect I followed all the right protocols and I did everything that they told me to do I am not going to pay that money they must write it off and send me an apology firstly they offered me bad service and now they are rubbing it in my face. I HATE ABSA NEVER AGAIN.
