Disgusted with African Bank

Abo****ely and truly disgusted with African Bank service and systems. Have 3 personal loans with them, and a credit card, and pay my accounts 100% every single month. I have attempted to apply for further credit, and the system declines everytime with the reason "There is record that the applicant has existing African bank account/s which is currently in arrears. We are unable to consider any further credit until such time that the arrear amounts have been repaid in full." Called the customer service department, and they refuse for you to speak to a team leader. The so called team leaders "promise to call you back", and that's like waiting for Eskom to turn the lights on, it never happens. All they can do is say "we are sorry sir, we can see your accounts are not in arrears, so we going to log a complaint, which takes 7 business days to resolve"? I am definitely going to take this up with Banking Ombudsman, the bank accuses you of being in arrears, when you are clearly not. Disgusting!!!!!
