Very poor feedback/response from MTN!!!!!!

I have been a victim of Identity theft - someone stole my ID number together with my banking details - and opened up contracts at MTN and Telkom. This started happening from April 2015. So I have reported it to the police - and even registered at The Southern African ***** Prevention Service. At Telkom they raised the issue with their legal department and sorted it out. So I have complaint several times at the MTN department , sending several emails - made several calls.. and every time I had to send the same documents to several people with the same reference number - I even got response saying that the Legal Department will get back to within 48 hours. Its been a month - and none ever got back to me. I wanted to apply for a personal loan at the end of September as I need some extra cash for my wedding that was on the 3rd of October 2015. The Bank declined my application due to my bad credit record - because of the MTN debit orders that was not paid - debit orders which is not mine!! Now I am talking about debit orders which is more than R130 000. I need my name cleared at the credit bureau - as this is affecting me badly!!! How long should i wait????
