comcast can suck a dick. I had those assholes send me a bill for an unreturned modem rental after I cancelled with them - a modem that I fucking owned and bought with my own god damn money! they sent that shit to collections after I told them to go fuck themselves - had to threaten to take the collection company to court over it for them to finally fuck off (and they did, never saw a ding on my credit from it). it wasn't a lot of money but god damn I was willing to fight over the principle of that bullshit.
