March 16, 2026 The customer service for Quantum Fiber is the most horrible I've ever seen in my life sadly. Today the customer service gal named Deanne or Deanna, I couldn't understand her, that I got was rude, she kept making me repeat myself several times throughout the phone calls because she wasn't paying attention, she hung up on me three different times and I had to keep calling back, and I asked to talk to a manager several times and she absolutely refused to connect me to a manager so if you ever have any problems with this service guess what you will not get connected with a service manager to resolve any issues because the customer service people that answer the phone are very controlling and they need to know every single detail before they'll even think about POSSIBLY letting you talk to a service manager. Our service was supposed to be set up a few days after we paid for it and it didn't end up getting set up for 3 weeks! Don't waste your time or money!
February 25, 2026 Horrible service and extremely unprofessional. I work from home and speeds are the slowest I've experienced. Additionally their techs call off and leave you without service knowing you are dependent on their service for work. My appointment was cancelled via a text at 6am , which is extremely unprofessional almd the. They reschedule another appointment for 10 days out on a Saturday that I have a funeral to attend. Representative Jason don't even offer or attempt to find another appointment time Disgusting and unprofessional! I have never been treated so poorly and will let everyone know of my experience with Quantum and after losing an immediate family member.

December 27, 2025 Sometimes our internet goes in and out and needs to be plugged in. Once it’s plugged back in though it goes pretty fast. It is a struggle to get someone out to help if our internet goes completely down, but when they show up the service is always great. We only wish that the costumer service over the phone was better.
