A short story about crappy customer service and persistence.
We had Dish for our home TV service. As far as pay TV providers go, Dish is a good company, in my opinion. Helpful/responsive customer service, competitive or even industry-leading feature offering, reliable, etc. But expensive once you get past the new customer discounts.
On a whim, we switched to DirecTV. The new customer rates cut our bill in half. The DVR appeared to have some superior features, features that we actually cared about. We were also sold on a few incorrect statements by the salesman, but so be it.
