Dude lives in the middle of nowhere. There's nothing wrong with Comcast not offering him service, there's something wrong with them claiming they did when they didn't.
Additionally, the homeowner should have been more diligent that his home in the middle of nowhere, with no cable box, would actually have cable.
Internet over 4G really isn't that expensive, and that's what he uses now. I'm surprised that doesn't work for him.
