********** activity in my account

I have ran out of words to say, after dealing with Telkom, every month I'm getting statements of bills that I don't know off, 2 contracts were taken under my name which are **********. Got a bill of R3599 and now a bill of R8000, they said the investigation takes 72 working hrs,and I'm still waiting. Spoke to more than 6 different consultants and team leaders who refused to come on the lines when I requested for them since Jan. I am still waiting for the feedback cause I'm tired of calling and getting such pathetic service. Sent them my ID copy and the affidavit as requested,but instead this bill doubles and I'm threatened that the account will be suspended. I demand proper service as my payments are always on time and have never missed any, can I get value for my money or that's too much to ask????
