Quantum Fiber

My provider, Quantum Fiber is really good in terms of speed and ease of usage! However, when I first moved into my place, there were a couple of hiccups that kind made the experience less pleasant as compared to cable service. The technicians who installed the internet did not do so correctly, and I was left without internet for several days, almost a week! This was SO frustrating, especially because I work from home and really like to use streaming services! This disrupted my work and ability to watch entertainment a bit. The technicians were nice, but initially suggested that there was nothing wrong with my service and that I hadn't set up my account properly. That was so rude and more frustrating! Plus, it was pretty hard to get into contact with them in the first place - no one would answer the phone and I was constantly being given the run-around: being told to call another extension, only for that person to tell me to call the original person I contacted. And on top of that, they were SO sassy for customer service. When technicians FINALLY came out, they still couldn't give me an answer about why the internet had issues. They FINALLY figured out they installed it wrong and had to open all the places in the ceiling where the cords where to fix it. But I'm still very grateful they could and that I eventually had internet :). Ever since then, it's been smooth sailing, haha!

I have overall been very happy with our internet service as far as speed and pricing. Unfortunately, customer service does seem to be lacking. In the past when we’ve had issues with our internet service, we haven’t been able to get ahold of someone for hours, and when we can, they’re not able to help. But me and my spouse both work from home, and the speed and capabilities of fiber have been really good. It can keep up with all of our devices really well.

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!
