Can I get help for them saying I have a zero balance then was told that I don't?

I had a cable service. Then was foreclosed. Company then wanted me to pay an early cancelation fee. When I called in one day regarding my return of my dish equipment, I was asked why I had an outstanding bill. I then explained why. I was then told not to worry about this that this bill since I was foreclosed, will no longer be billed. Then later, I called back to make sure all the equipment had been received. That is when I was asked, when the balance was going to be paid. I explained what had happen when I called in. That is when I was told that the customer service rep was not supposed to do that. That is when I was told again that I had a bill. Sixteen months later, I still am homeless, live in my car and have no way to pay this bill.
