Their service / support STINKS!
Our cable went out during the last Bulls-Heat game. No signal on either set.
Called Comcast support. One "tech'. One supervisor. Almost 90 minutes. Neither could understand that settings don't change by themselves when nobody's holding the controls and type F connectors don't come loose by themselves.
After running out to check the line into the house and pulling out the basement ceiling to check the splitter, it was miraculously announced "There's a service outage in your area. It'll be fixed by midnight".
After an irate letter to the CEO of Comcast, I found out they have NO WAY of knowing if there's an area-wide service outage.
THEY HAVE TO WAIT AND COUNT THE NUMBER OF COMPLAINTS COMING IN FROM A GIVEN AREA!
