FNB Premier Account Closure

I have been trying to close off my account from July and I was told that there's a pending transaction on my account so I must wait until they were processed and then close off the account which I did then there were attempts to debit money from the account which has incurred fees. I was then told we can't close off the account because it's in arrears and I need to settle them first which I did and when I requested for the closure, I am being told that there are pending transactions linked to my account but when I checked my banking app, there are no pending transactions showing. I tried using the secure chat option and that consultant told me that I have to wait for my account to be billed monthly charges then they can close off the account. WHY AM BEING SUBJECTED TO ALL THIS UNFAIR TREATMENT FNB? WHAT IS IT THAT I HAVE DONE TO THIS BRAND THAT MAKES YOU TREAT ME THIS WAY. I'M NOT A RICH OR WEALTHY INDIVIDUAL THAT WOULD MAKE YOU FEEL LIKE YOU ARE LOSING OUT ON GOOD BUSINESS.

PLEASE ALL I WANT IS TO CLOSE THE ACCOUNT AND MOVE ON.
