Dish Network - Echostar Continuing to receive charges and service has been terminated for months Englewood, Colorado

For two years I had Dish Network service in a bundle package with AT&T.  In or around March 2009, Dish Network and AT&T ended their relationship and Dish Network changed my fees without any notice to me.  After numerous phone calls they agreed to lower the price, but not to what I had been paying previously. 

After that every single month my charges went back up and I would have to call Dish Network and beg them to adjust my charges back down to where it was supposed to me.  Finally in June, I told Dish that I did not want their service anymore.  This was too much of a hassle with their poor customer service. 

Then in July 2009 my satellite service on one of my TV's quit working and Dish Network told me that I would have to pay them if I wanted them to fix it.  I declined to pay for this and I told Dish that I did not want their service anymore because it had been just a terrible hassle.  However, I did continue to pay my monthly charges at that time.

Around August 20, 2009 I lost complete signals on all my TV's.  I had no picture at all on any TVs in my home.  On August 30, 2009 I had Direct TV installed at my home.  I then tried to get this service cancelled from Dish.  I have called them several times to cancel and each time, I am told by the person I spoke with that I have to speak to someone else; that they are not authorized to cancel my service.  However, each time I am transferred to someone else, no one has yet to answer and speak with me.  Since that time Dish Network has continued to bill me every month.  They call my home and they call my cell phone numerous times aday.   I have tried unsuccessfully to talk to someone about this. 

Finally I wrote a letter to Dish Network complaint department about this and a few days later I received a phone call telling me to return the equipment.  I did that immediately.  I received an acknowledgment that Dish had received the return equipment.   However, Dish is continuing to bill me for ongoing service.   When I have attempted to talk to someone at Dish Network, I can only get a recording that my service has been terminated and if I want it back to pay the bill my service will be restored.  

 I don't want their service back, I want them to stop harrassing me and to stop billing me for service that was terminated back in August 2009.
