Closing of bank account in 91days!!! Ridiculous FNB!!!!

I called FNB on Friday 27 March 2020 to close my personal cheque account. The lady assisting me was very professional. She assist me friendly doing so. She ask me a question - mam, are you under debt review? Instantly I was exploding inside. I was removed from debt review on 20/1/2020 by court order. Now she’s telling me, according to my debt review status it will take 91 days to close the account!!??? I don’t have any credit outstanding and only have vehicle financing and insurance on my credit profile!! I asked her am I still listed at FNB as “under debt review” and she said yes. This is a friendly request to FNB to close both my personal cheque account as well as my business count immediately, and if not so, I will NOT pay any bank charges raised and accumulated on the accounts. After many many years being a client of FNB I close my accounts eventually after a reconsideration. The services and bank fees has becoming ridiculous!! I really would like FNB to look into this matter it blows my mind that you have to wait days to close an account on which I don’t owe money!!!!??
