3rd attempt at closing account at African bank

Hi good evening. Firstly l apologize for replying only now. Has to go to African bank several times and received a call from them as you informed me. I ended up agreeing on paying another settlement agreement of R797.00 payable 30/06/24. According to their system l paid in full but the account wasn't closed in 2021and when the made a deduction the following month of R997, reversed it which put me in arears. Today l received a SMS from the lawyers of African bank informing me that I will be paying their admin bill which they will send me after paying the settlement amount end of June. I am deeply disappointed. I can not understand why they can not admit the fault on their side by not closing the account and taking legal actions against me for more money. This will be the 3rd attempt on closing the account and dispite it all are now on a bad credit report at the Beauro😭
