I'm paying for their "Gigabit Extra Plan" which shows a high speed from THEIR rigged ISP speed test. Other speed tests shows at least 70% less than what Xfinity's "Speedtest" shows. I experience low speeds, lags, latency issues, to name a few consistent problems using Xfinity services. Very disappointed with this company and it's ONLY because they're a monopoly (Capitalism best practice) that there's no other option but to use this company! Disgusted with this BS!
I have had ok results with the actual internet. Even after I increased my speed and bought a new router it doesn't seem as fast as should. As far as customer service goes, i have had one really bad experience, but usually the people are nice and helpful. Definitely beats dealing with Comcast.
