I've been a DirecTV Center Ice customer for years. For the most part, I'm happy with the service. But, they seem to be good for a screw up once or twice a year that forces me to miss a game.
Today seems like one of those days. The Avalanche are on Altitude today at 3pm eastern. DirecTV seems to think they are on NBC and so don't have the game listed on any of the Center Ice channels. I have a sternly worded email out to them (okay, less on the "sternly", more on the "worded" part), but I'm not sure if it will be in time for them to fix this boneheaded mistake.
