Nedban putting wrong info on cutomers profile!

Wanted to apply for a personal loan. I already have a personal loan at Nedbank. When they checked. They informed me I was under debt review. Which I'm not. Told them its wrong info on my profile. They were persistent that Is was me. Told them to get a credit record of me. Which proofed to them, that I'm not under credit review. They still didn't want to help. I had to get forms to proof I'm not guilty. Then still they cant clear my name. Its been a week now. No answer as to what is going on! Just the same response. We have to wait for the lady.... So I would like to know if there is anyone other than Lindiwe or Chris the bank manager that can help me!!???
