Comcast is the biggest joke I've every had to deal with! A Sales rep attempted to install our cable three times and failed each time, making myself and my wife have to miss a couple hours of work each day.
He over guaranteed and did an excellent job of under delivering. Not only that, we recieved our bill for 5 days of cable and two days of internet and it was $168!! For something as simple as cable, comcast has done a great job at showing that they do not have the infrastructure in place in the market to meet customer expectations.
Not to mention they don't want to retain their customers when they charge them for services that were never received. Its embarrassing.
