Incompetence!!!!!

I have settled both my African Bank accounts in September 2018 to this date the accounts have not been closed and still show on my credit profile. I have called the lawyers whom the account was handed over too, they advised that African Bank should update their records. Called African Bank this morning and no one is able to assist they keep on transferring me. It's over 3minths since the accounts were settled but their records are still not updated is this even legal????? Can an this be sorted out today
