Cannot close credit card account

Good day,

I have closed my ABSA account a while back because of the poor rates and the overall level of service. Now I tried to close my credit card as well. The consultants keep on giving me the wrong settlement amount which leads to additional payments of 50 cents. This delays the process by a day or 2. I received a settlement amount for yesterday and called them to close the account once the amounts reflected in the account. The consultant said that no one was picking up and they would call me back. This was after she verified all my details and took down my contact details. No one called and now today when I called back, there is again another settlement amount of 50 cents. I am going to cut up the card and forget about it. Do not hold me liable for any monthly service fees or interest as I did my part in trying to settle and close the account.
