Comcast didn't used to be as bad as it is now. When they first started up in the 1980s, they actually had moderate prices, and had a pretty good channel line-up. But then, as time went on, they steadily increased their monthly charges. A couple of years ago, I discontinued their "classic" plan (which was their average plan, it had gone up to $88 monthly), and signed up for their "economy" plan ($47 monthly, but the channel lineup is so limited that there's often nothing on worth watching, so I just automatically tune in to the CNN news). I'd drop it altogether, except that I need it for the reception.
Apart from the cost, and the very limited channel selection, I can't complain about their service, though. The telephone people are always courteous, as are the repairmen, and they fix any service interruptions promptly.
