Bank Account closure gone wrong

I logged a call to close my bank account about 3 weeks ago. I was told it was an 8 day process which would allow me enough time to pay any outstanding amounts and transfer any balances to a preferred account. I balanced everything out to a R0 balance only to receive an email demanding R150+ in order to close the account. When I called to enquire, their credit department was able to tell me there is no outstanding amounts due. I am still awaiting confirmation my account will be closed and in the interim I will likely be billed the monthly premium just to keep the account active. As usual, all too quick to create an account but ever so difficult to close one. Just when I was second guessing my choice to close the account, you made it easy to cement the decision.
