Lack of performance

About 3 weeks back i went to fnb to close my cheque account ,they told me sorry there is a waiting payment so i must come back next week, the next week i went there they said sorry i opened the account in musina so i have to sign a paper which they will send and close the account, after 2 weeks i went back to check if the account has been closed but no progress, todays consultant got to the problem but then said she cant close my account because the teller is closed so i called the floor helper \tracy"she then said they can make a plan to close it bit when they tried the problem started all over and for me it is absolutely unacceptable for a branch to take more than 3 weeks just to close a account and the consultants gets mad and starts to roll her eyes at you when you dont understand that is not fnb standards"""
