Stil awaiting response

Good day, I have made requests via phone as well as email to settle my standard bank credit card account . On Friday 02 October I requested what the outstanding balance on the account is and were told its R284,00 so I paid R290. After making the payment on Saturday 03 October I've contacted the credit card department by phone and were told the settlement amount is R17,00 however on Monday 05 October I received a statement via email that the balance now is R50 and so on 05 October I've also send an email to [Email Removed] to request the right /actual outstanding balance. Until today 14 October I have still not receive any response from Standard bank regarding this matter. I have stated that I have no need for this account and don't receive any service from you but I'm required to keep paying for something I don't use. I'm very dissappointed and think it's very unfair just because someone, somewhere is not doing their job. Can someone please resolve this matter asap.
