The blogger seems to have adequate grounds to file a civil fraud suit, wherein he might ask that he be made whole for the losses sustained as a result of the misrepresentation, or compel Comcast to act to make their false statements truthful. Basically, pay for the aggravation, or do whatever it takes to provide service to the house, at their own expense. I'm not a lawyer, but this guy should definitely go for a consultation with the ambulance-chasingest, billboard-advertisingest attorney in his county.
And then demand a jury trial. There is no way that any given 12 people from the jury pool could see the facts of the case, and not want to curbstomp Comcast into oblivion.
Might be a good idea for the next house.
Comcast could be held accountable for other reasons, but not by a contingency.
