Standard Bank, Moving you backwards

I have been a loyal client for over a decade with this bank and I was not happy but too busy to change bank and the admin was just tedious. In May i visited my local Standard bank branch to close my account and i was advised it will be done but now the account is sitting on a minus two thousand rand for reversed debit orders and this is annoying because they are just watching it pile up so they can call me and say pay and we will close the account. I am not interested in continuing with this bank because they take your money and offer no service, just arrogant people working there. Discussing to say the least, shame on you.
