Harassed daily for a ***** deal done on my name

A ***** deal was done on my name at Nashua Mobile, just before they could close down. Accounts we're handed over to Altech Autopage, I tried to rectify the problem with Altech, but they refused to help me, saying that I had opened the account and I am responsible for it. I tried to gather proof that it was a ***** deal but they would not listen to me. Then the account got handed over to Nudebt Management before Altech Autopage could close down. I have sent an email to these people with all the information, but still I am being harassed on a daily basis and they have even gone as far as putting a trace alert on my credit profile. I am not a bad payer but because of these ********** companies and their staff I have now been listed as a bad payer. I refuse to pay for something that I have not taken and will not be sucked in by these **********. I need this to be resolved and my name cleared immediately.
