XFINITY Cable
August 10, 2025 Unfortunately, the area in which I live only allows me to use this provider and they know that so they do not offer many discounts and if their service isn't good they know we have to live with it. I really wish we had some competition so that I could choose another provider or have a bargaining chip when negotiating our rates.

April 08, 2023 The experience with Xfinity seems to vary based on where you live. We're happier with them now that we live in a place where they will compete to keep you. So while it's a hassle to have to call in yearly to get on a promotional contract, knocking 30-40% off the rate makes the bill acceptable. We previously had some issues with Xfinity not honoring prices they quoted by phone but they now let you preview all the paperwork digitally before signing and get copies by email afterwards. I find that a big improvement.
