Awful account closure service

I have had an awful experience with the Sandton city branch. I closed my accounts including my credit card with a consultant Thulani Nakeli and today I receive a credit card statement (for an account which should be closed) stating there is a balance to be paid...how can I pay for an account which i was given written confirmation that the account is closed and after the initial instruction was given I had to follow up three times before it was done. After the first attempt I physically had to go to the bank to resolve only to be told nobody but the consultant who initially helped me can help and he was not at work! i have sent emails and called leaving messages yet received no response. this service is awful and the exact reason I moved banks in the first place. If Standard Bank is interested in getting there money how about you call me instead of making me hold over 15 minutes on your line and still not being able to resolve my issue!
