I have the Comcast Xfinity bundle that includes cable, internet, and home phone service. If I were able to accurately describe how bad the service has been, and continues to be, you would shake your head and wonder why I bother to keep their service. Indeed, I question myself the same.
I have only myself to blame because after the 4th service call to get the cable to work I should have dropped them like a bad habit. Besides the service calls for the cable, I've had 6 service calls for the internet. The internet is either slow, slower, or broken at all times.
When the service technician comes out, if the internet is working at all, I show them how slow it is by trying to watch a video on YouTube. It takes at least 2 minutes for a YouTube video to buffer so it can be viewed. The technician shakes his head, says something like, "Oh yeah, that is slow. It shouldn't be that way." He hooks something to the modem, remarks that the modem seems fine, then makes a phone call. This always results in, "Someone else is going to look at the lines." or "I think they are working in your neighborhood today so that's why it's slow."
Nothing has ever been fixed by Comcast, ever. Oh the cable? We hired a private contractor to fix the cable so we could watch television, cost us $275. My neighbor down the street has DSL. I've been leeching off of his wireless for over a month because my Comcast internet doesn't work. I think I'll slip him a $20 every month and divorce myself from Comcast. Buyer beware if you're thinking about using Comcast.
