Outstanding Customer Service

on January 13, 2021

I am a long time customer of New Wave Communications (Sparklight). Although I have never had an issue with their phone and internet services, I did recently encounter issues with my online account on their website. I was unable to make simple, basic profile changes to said account; but instead was directed to call them via phone. Imagining countless minutes of my time to to do so - I was exasperated; but call them I did at the number so directed. I had several issues to bring to their attention and I am overwhelmed at the response I have received. Much to my chagrin, I did not record the names of the individuals I spoke with; however, I can say that both the individuals I spoke with were knowledgeable and extremely courteous. Much appreciated. I made one phone call, received two phone calls in return and one email from this company concerning my issues. The representative I originally spoke with and a gentleman from the IT department reached out to me via phone to provide an update on the status of my issues and to notify me that they were indeed working to resolve said issues. Kudos! to them both, especially in today’s age where one is constantly bombarded with relentless recordings in an effort to reach out and speak with a human being. This company made it easy. Again, much appreciated.

Outstanding!!

This is the best service along with the astonishing speed. Tech was in my apartment for less than 10 minutes. Thanks again, Sparklight!

100 Mbps CenturyLink Internet

on September 19, 2019

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.
