Absa credit card.

I went to the Vredenburg Absa Branch to close a credit card only to find out last month that the account was never closed. Paid generated fees into *** which I was given and the payment came back. There is no such number. This week I got a sms to say I am in arrears and need to make a immediate payment. I was give ***. Only to find out that that number is not in use either. Now I paid money into the credit card and hoped that it will be closed... all I need to do is close the credit card....why does it have to be such a hazzle.
