Tried to contact Direct TV because I lost signal on one unit only. After calling six different numbers (first five were disconnected), I finally got their canned tech service. The computer walked me through exactly the same trouble shooting steps I had followed in the book left by the installer. Five minutes I was allowed to speak to the rudest human they could find.
The call was concluded without any additional information or resolution. I hung up got on line and resolved the problem by following a recommendation I found on-line.
Twenty months and counting to change back to a REAL communication provider.
