Customer Reviews for Internet Service Providers in South Carolina
Customer Reviews

Spectrum Cable
November 17, 2025 I've been very pleased with Spectrum's service of late - we rarely lose cable/internet, even in storms, and if we do have issues they're very good about communicating by text. I have a grandfathered old Silver tier and the price is a bit high for what we get. They have added "free" streamers like Peacock and Paramount so that lessens the sting a little. Overall, I'm happy with them.

FTC Fiber
January 04, 2025 FTC's been great. They're actually one of the oldest telecoms in the country. Been with them almost 50 years actually, and the internet is just something bundled with the now-obsolete landline. I could up the speed even more to 1Gb/sec but what we have is good enough for a couple TVs and PCs plus a slew of IoT devices. It's about $85/month right now. I also have a dedicated mobile-phone line on my Chromebook but only use it very rarely.

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.
