We had DTV service from the beginning when you bought the equipment and installed it yourself.
They are a much different company now.
4 years ago I had enough and when we bought another home and moved in we went with cable.
DTV fought me all the way, even after some 15 years. They tried to tell me I had a two year contract in force and I told them to prove it. They attached a $500 (I think it was) early disconnect on my credit when I refused to pay it without proof.
They referred my "collections" to 3 companies forcing me one by one to send what I had to them to get rid of them.
Finally I notified the last collections company and DRV if they contacted me again or referred this matter or listed it on my credit report I would sue them.
Enough said, they dropped the matter entirely.
