Refusing to close my account

So after 28 years of dealing with this bank on the 28 September I just had enough, I went to the branch to close my account and no success, my reasons for closing my account is that the bank keeps taking funds and what’s worst I keep owing the bank and there’s traces of why, Thursday I went to close this account and no success, the consultant told me it’s not possible, there’s was a withdrawal I had made of R100 on Thursday which was taken from available balance but remained in my balance as pending till this morning, to my surprise this morning my available balance went to -R193 making this even more impossible to close this account. I’m so disappointed and I I’ll never deal with this bank ever again, I cancelled my policies and yes a great loss, but I have had enough and everytime have to complain here on Hellopeter taking so much time and unnecessary complaints when the bank could just play fair. This bank is very unprofessional and I just want out and whatever monies they’ve taken must be reversed and close my account.
