Customer Reviews for Internet Service Providers in South Carolina
Customer Reviews
Greg M.
CarolinaConnect Fiber
November 13, 2026 Rudest supervisor is Christy. We were told we had to use our previous equipment at our new address in the same zip code but only a soft start was needed because the previous owners of that residence, but Customer service and Christy said no. Said we must talk with Tech support. They said no. So, we'd have to schedule a date and wait hours for someone to show. Meanwhile I work from home and need the Internet to work. Christy then says IT can do it tomorrow at 8AM, but I have a 9 AM meeting I must make. She won't give us IT's number to arrange a better time, so we say we will have to look at other options. She then calls back wanting to cancel our current service now. Can you believe how rude and petty this woman is. We can't have another appointment for a soft start or new equipment installed at the new residence, so I can at least continue working in the meantime. If you treat all your customers this way. You deserve no customers.

July 22, 2026 Several outages lately. It was down today but it is running slow. I put in a ticket and the speed of the response will determine wether I go back to Spectrum or not.

June 12, 2026 The price of my family’s internet connection is really cheap. It is around $20 per month and we have been with this provider for at least 10 years. However, there has been a decline in the presence of this company and they appear to be losing lots of customers. There is always some WiFi connection issue almost everyday, but it is minor. My phone may lose connection but my MacBook, iPad, and TV is still connected. Overall, for the price and in comparison to other WiFi providers, I am overall satisfied with my internet.
