Hassle to close credit card account

I am extremely unhappy with the service and charges from Standard Bank. Over the years I have closed my cheque account, savings account and now wants to close my credit card account. I went on Thursday to the Galleria Amanzimtoti branch and queued outside the door for some time - no chairs were provided. Once inside the branch I sat on a chair in queu for another 90 minutes before being told that I can't be helped at the branch to close my account. I had to settle the outstanding balance electronically from home otherwise I will pay a cash deposit fee. That was one of the reasons why I am so unhappy in the first place. I owed +- R450 on this account, paid R100 last month and my capaital balance was R17 less after interest and admin fees ate the rest...I would rather throw money out of my car's window than pay the fees to Standard Bank. I then left fuming and paid the balance. I called today only to find that no balance are reflected on Standard Bank's system and I cannot close my account. This is not right. It didn't take them 3 days to offer me credit and can't take 3 days to close this account. Standard Bank is delaying to charge further admin fees...I will not accept this and will take it to the ombudsman if necessary. Stay away from Standard Bank.
