Credit Report

I'm soo disappointed with them, my account was handed over and I settled it last month I have made numerous attempts to try and get this account removed off my name only to find that African Bank is not helping me I eventually went to their branch and made a phone call from there and someone answered and told me that my account is locked and that I needed to go to the branch and I responded and told her I'm at the branch and asked her to tell the branch consultant what to do and she told her then hung up on us, we tried again and got cut off again, eventually got through to someone and she tried to assist and told me that the account was only paid this month on the 7th and only closed on the 10th they will send a request today only to transunion and it will take 21 working days for it to be removed, My issue is that I paid last month and if I didn't call today they were not going to remove it and they're telling me that I should wait 21working days I'm trying to apply for credit and it's still showing on the credit berau. I need this sorted out sooner than the 21working days. I can't wait for that long African Bank has to remove it from their side. I was told a manager by the name of Rea Kgoathe, Mosebi Sophia African Bank will call me, to date I have not been contacted. I cannot be made impacted by African bank's internal processes all those things have nothing to do with me.
