I used to have Xfinity and I loved their services, particularly the internet. It was fast and reliable. As for their costumer service, they have one of the best out there. I had to end it though since I was paying ~$170 a month.
We use to have Comcast, but their service kept ****ing up and every time we had a repairman come to our house he and my dad would always get into it. the only thing I like of Comcast is On Demand.
I thought Comcast was the worst, and too damn expensive for it. I switched to Dish and now I wanna shoot myself sometimes TERRIBLE service. And there's **** for OnDemand, which is the best part about cable.
