Cox
When I was getting Cox installed after 12 years the contractor for Cox who runs the new lines almost got sued by Dish Network because the contractor ran the new COX line to Dish Network's Box (where everything for Dish Network comes together). This after I told Cox the day before that all this stuff goes to Dish Network.
The only reason this nearly happened was because I had an issue with Dish Network, and an installer came out, and noticed the line from Cox..
It took two weeks to get a new line dropped again by Cox even after Dish network gave Cox a buzz.
