*****ulent Contract

I would like to report MTN, last year December two *****ulent contracts where open under my name by MTN. I reported the issue and submitted the necessary documentation but still the problem is not resolved, the problem is that the money keeps increasing of these contracts that I have no knowledge of and now they have suspended my line because according to them I owe them. My line gets cut off every month, every month I have to call them so they can unsuspend it which is very frustrating, this is also affecting my credit score. Mtn is so *********** from last year December i'm doing the same thing.
