Have had nothing but problems with Comcast since we got their service eight years ago. We have business class internet. When they sold it to us, we were told that we would have four hour response time, and better service than home users. WRONG !! Now they do not give promises for response times. They may tell you that it will be sometime today. Not even a time window.

Our Internet and TV service quality has been poor since day one. The lines and circuits have not been updated. We are not allowed to get the newest modems and boxes, due to old contracts with Scientific Atlanta. Our friends just a few miles away have the newest circuits and boxes that Comcast has. Our area is treated like an after thought. Everything in our house, and outside the house has been replaced at least twice.
If there were any other options in our area, especially for Internet, I would jump on it in a heartbeat.
