We have waited 3 months to get a temporary line buried. we were told on 4 different occasions that we had a date and plan to have it buried and each time it never happened we would call and be told there was never a request submitted for it. It’s unbelievable I don’t know how we will ever get it buried. We have to…

Quantum will not change or will not let me change my plan to a lower tier plan. I have “changed” it 3 times so far and have had 4 chats and they don’t see my change even when I provide several screen shots with time stamps proving that I didn’t and submitted it and that it was accepted. They want more money and will…

Quantum Fiber’s customer service has been highly disappointing. I have reached out to them five times over the past month to resolve an issue where a cable was left exposed in the alley, with each interaction resulting in an appointment being scheduled for burial. However, no one ever showed up to complete the work. When I followed up with customer service, I was told…

Customer Service is horrible. The first few months of service had no problems and then all of sudden I started receiving email messages about “outages” and how the company was sorry for the number of service outages. Very convenient that customer service had no answers. It was basically like having no service at all.

I’ve been trying to get technical issues resolved since our service began on August 28th. Our internet/wifi drops every 15 minutes and only recognizes 2 devices at any one time. The only two options to get support are chat or phone so I’ve been at their mercy trying to get through. (Don’t try emailing – they don’t respond. I tried that twice two weeks…

I have had more than half a dozen appointments over two weeks, but they have not kept one so far. It’s so frustrating when they just change the date and time of appointments at will. It isn’t an appointment if it cannot be kept. Very disappointing service.
