FNB Business account Service disappointing

I called FNB In April in order for them to close an account i had with them - the FNB consultant said i must deposit money in the account equal to the monthly service fee. On the 5th of May 2022 another consultant called saying i needed to make sure that my account either has a zero or negative balance in order for her to close the account, I confirmed the account number over the phone - however till today the account is still not closed - instead only the savings pocket linked to this account was the only account closed. The FNB business accounts consultants have failed to help me with a simple request - closing of an account.
