When you sign up for Comcast Broadband Internet Cable Service you assume that it is for unlimited service thats what there marketing material touts it as. But apparently when you go over a certain volume of traffic you get a nasty letter in the mail. I think I would take the letter they are sending out to users and gather all of the marketing ads and materials they have and visit one of those lawyers that have full page ads in the newspaper saying that specialize in suing people and sue Comcast for false advertising.
