Can I do anything to remove my name from account thay was not authorized?

In February of 2012 I started internet service with TWC. I have never recieved their service prior to this date. A month went by and I never received a bill. I ignored this since I pay all my bills online. Another month went by still no bill. I called and asked, they said it was sent. Come 3 months later, after calling them I am told there is. Outstanding balance of over $600. I argue that that cannot be possible, they direct me to collections - whom cannot find amy information on me. Needless to say after 4 months of continuous calls, the problem is finally identifies. Whem starting my account the representative reconnected my neighbor''s cable tv account, put my name on it, and because they owed on it, I owed. They correct the address, but when doing so moved my name amd all said debt to my new account, plus transfered overdue equipment charge. What can I do to end this headache of 5 months? Is there any legal action since they used my name on a account I did not approve on?
