Have you ever dealt with Comcast? I have DirecTV and DSL. If I have DSL problems, I call the phone company and say there's noise on the line. Since they have to respond within a certain amount of time for voice line issues, that means the line gets fixed in a timely manner. I could be wrong, but I don't believe that Comcast has any such requirement. They roll a truck when they feel like it. Worse, if you're only getting Internet, they cap your speed lower than if you were getting TV as well. Not to mention that when I considered going Internet only with them, they insisted on a two year contract but wouldn't say the price for the second year. I'm not entering a contract with someone if they refuse to disclose the terms of the contract. I don't even understand how that's legal. Plus they wanted to charge per foot for a line to the house even though I could just about reach the phone pole from the house. Then they wanted me to buy a modem, whereas the phone company provided a modem with wifi and hard wired ports for free, without a contract, and costing half as much.
They sent people door to door in my area last year. There's a dish on nearly every building still, I doubt it was worth the effort of knocking on doors. How bad does a company have to be to send people to your door to beg?
