100 Mbps CenturyLink Internet

We switched to CenturyLink and could not be happier. It is so much faster, has never cut out and had the best installation customer service. The price is also great.

Love Centurylink

on June 18, 2021

We have had Centurylink landline for literally decades. It was a no-brainer for us to use them for internet and landline when we moved into our new home. Our home was built in an area with their new fiber internet. They installed it on the day scheduled, at the scheduled time. The technician was great. Had it up and running quickly. Have not had any problems. Both the internet and landline are cheaper than we were paying Cox for just the internet. Had a very bad experience with our previous ISP. Kept dropping calls. Hope to have Centurylink for decades to come.

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!!
