I've cancelled my Comcast account. Cable boxes don't work. Functions on remote are inactive at this time.internet not functioning at all. DVR playback stops every 15 minutes at least. Sometimes more often. Three hours on the phone and three tech visits later NOTHING is fixed. I'm done. Switching to DIRECTV. I've had Comcast in Tucson since 2009 and it has become worse every year while the prices go up. Why does a company like this have a monopoly on cable service in this area?
