Paid up an account however this bank still has me listed under credit bureau

I had 2 accounts at African bank but due to financial problems I occurred I could not pay as per arrangement,however when I was able and willing to pay I was given a settlement amount for both accounts n settlement date was within 5 working days , paid up the account n received paid up letters saying accounts paid , However I’m very disgusted that such a huge organization like this was able to follow and nag me for payments when I couldn’t pay and now that I’ve paid up the accounts they can’t seem to do one simple task to have my name removed , I’m very disappointed and would never advise anyone to go to African bank !! I’ve spoken to 5 different ppl there and they all advise “it will be sorted “ I’m sick and tired of these blood sucking cruel bank .
