Account closure

I have been battling since the 11/03/2021 to close my FNB Premier cheque account. I have sent numerous emails and made numerous calls to FNB. With no assistance whatsoever!!!! This is extremely frustrating, as they are still taking their monthly fee and the account hasn't been used since the 11/03/2021!!!!! All the consultants that I have dealt with inform me, that they will escalate this matter to their team manager and provide feedback within 48hours! Still nothing to date....... 8 MONTHS LATER!!!!!!
