DirecTV I never signed contract, have no dish, no cable and no cord for their box. Being harassed for payment. Greenwood Village, Colorado

DirecTV is harassing me for payment of a contract I never signed.

I moved from my home in April 2011 and returned to my townhome from assisted living in June 2011. 

My original DirecTV contract from 6 years ago had been cancelled, the dish removed, the cable removed prior to my departure from my home. 

When I returned I started receiving bills and contacted them to inform them I had no dish, cable and no cord to plug in the box.  I asked where the box should be returned.  They said if the box was returned, I would have to pay for the entire contract term, which was 2 years.   I informed them I did not sign a contract, I didn't want the service, I had no dish, cable or cord and therefore, it was impossible for me to receive a signal. 

They have continued to harass me by calling me daily.  I have spent hours of time on the phone and no one will take any action.  I finally squeezed an address from them where they told me to address a dispute and have written to this po box in Greenwood Village, CO.  I live in NJ.  I doubt that I will ever hear from anyone.  I have just sent letters to the BBB in CO and NJ.
