I did complain. The thing that I was most upset about was that the links to the games were sometimes messed up. I think I missed chunks of the first quarter in about 6 or 7 of the games last year. And sometimes I would spontaneously get an error message in the middle of a game and it would take a long time to get back in.
I called DTV (not easy because they don't publish a customer service number--you have to dig for it). They acknowledged that they had problems with their service, but they insisted that their policy is to not provide any rebates or refunds, period!
They know they have you over a barrell. They make you pay the full $350 upfront. Then they make ZERO considerations for bad service. And they make no apologies. They simply tell you there is no recourse. I tried to escalate the issue somewhat, but got tired of banging my head against that wall.
It's unfortunate but true that DTV has exclusive rights. No competition = crazy pricing and poor service.
In their defense, it did improve over the course of the season last year, but still not great. I almost pulled the trigger and got it again this year, but finally decided against it.
