CLOSE MY ACCOUNT!!!!!!

This is literally my lost resort. Because I have no clue what to do.

On July 08th 2021, I wanted to close my account. I went into the Clearwater branch because I was tod there is no other way to do it other than going to one. I spend over an hour, and was told that I just had one more pending payment, and they will close it after that. And will be sent a closing letter. I deliberately went in on that date to make sure all my debit orders & bank fees were already out. Last week, I get a statement that I my account is ±R800 in the negative. I open it, and law behold, its bank charges and other fees that SB decided to charge me. On Monday 27th I go into the same branch, an again after an hour, they tell that I need to pay the R800 before they can close my account. I refuse because I did EVERYTHING required of me to close my account back in July. So after hours of back and forth, they say they will close, but they have to manually reverse the charges, which might take a while, so they will mail me the closure first thing Tuesday morning. I now cannot get hold of the banker who assisted, but now I am being told that the account is not closed and I have to go to the ranch to close it & that I still owe monies!! I cannot afford to be spending hours at the bank to close an account, and being told it will done and then it doesn't get done. And no, I should be paying penalties for a services I closed. What must happen now????? Someone please assist me.....
