Great Service

on October 06, 2019

First time Xfinity subscriber. Exceeded my expectations. I can honestly say I was very impressed with all aspects of Xfinity. I just purchased a home in Delray Beach FL. From the initial appointment call to complete installation, Xfinity exceeded my expectations. Very impressed with the Tech. The tech arrived early. He introduced himself and ask me about my expectations. He explained what he was going to do and would have me watching NFL football today. Walked me through the setup and all options of the remote. I ordered cable and internet. I will say the internet service is faster than others. Very impressed with Xfinity.

Amazing service!!

on August 31, 2021

This was my first time using Xfinity cable services and I absolutely loved it! I never had an issue. Unfortunately, I do have to disconnect my services, due to moving to a location where Xfinity is not offered. I wanted to recognize the service rep, she was absolutely amazing. She answered all my questions on how to cancel my service. She even gave me the mover's department contact to help me find a new and awesome wifi system in my new area. I was blown away by her kindness. She wished me good luck with my move and gave me a positive outlook during all of my frustrations. She was so kind and comforting and deserves to be recognized greatly!!
