I live in Minneapolis and signed up after being sold Quantum Fiber by a door to door rep.

I live in Minneapolis and signed up after being sold Quantum Fiber by a door to door rep. The service speed, up and down, to the house was as promised, but there have been frequent outages and my wireless connections drop all the time and only offer 500-200 mbps download speeds. The equipment installed is terrible, not configured with the latest security protocols, and is barely useable beyond one room, where the WiFi pod is located. Customer service and support is truly terrible. I have contacted them multiple times over two months, was outright lied to, and was not even able to get a straight answer about when I could get another pod to see if it would help the issues. I finally gave up and cancelled since Xfinity is now offering comparable pricing for comparable download speeds but not upload, of course. I will be sticking with Xfinity until USI is available in my neighborhood.

One star — loyalty means nothing here I’ve been a paying Quantum Fiber customer, on time, every month, keeping the lights on for this company. So it’s beyond frustrating to watch them advertise their best prices exclusively for “new customers” while existing customers like me get left out entirely. Think about that logic: the people who’ve actually been loyal and reliable don’t qualify for the deals…
One star — loyalty means nothing here I’ve been a paying Quantum Fiber customer, on time, every month, keeping the lights on for this company. So it’s beyond frustrating to watch them advertise their best prices exclusively for “new customers” while existing customers like me get left out entirely. Think about that logic: the people who’ve actually been loyal and reliable don’t qualify for the deals — but a stranger walking in the door does. That’s backwards. Rewarding new sign-ups while taking your existing base for granted isn’t a strategy, it’s a slap in the face to the customers who got you here. If Quantum Fiber actually valued loyalty, their best available pricing would be offered to everyone, not dangled as bait to chase new accounts. Until that changes, I can’t recommend them. Take care of the customers you already have.

If you work remotely stay far away. You will have a week long drop in service every three to four months. They will randomly cancel your appointments based on an automated algorithm that claims your service is fixed. You won’t find any sympathy, nor any viable compensation for their tomfoolery. Run, don’t walk, far far away from quantum, cause the only high speed you’ll…
If you work remotely stay far away. You will have a week long drop in service every three to four months. They will randomly cancel your appointments based on an automated algorithm that claims your service is fixed. You won’t find any sympathy, nor any viable compensation for their tomfoolery. Run, don’t walk, far far away from quantum, cause the only high speed you’ll find is the amount of time it’ll take for you to regret signing up.

I think Quantum Fiber is a nice and flexible Co. That is pretty good at customer service and the internet itself!! High speed internet!

Go with Xfinity. Save your time. This fiber is pure trash. And no local offices. So if you cancel, you have to ship the equipment back, and it gets lost. 700 taken from these.. I called repeatedly but no one cares to help. Wired internet was slow.. WiFi was flaky. For the price, and for what fiber was meant to be. I went back…

Quantum lost my account. I’ve had an account for over a year, and suddenly I can no longer log in to my account. Customer service can no longer find my account or any record of it. What?

The absolute worst customer service ever. They rescheduled 3 times. When they finally arrived on the 4th try, they didn’t have all the equipment needed for installation.

When I signed up for service, I was told there were no issues, and we could get service. They quickly took my money, and we scheduled installation for approximately 9 days later. The day before, I was told that there would be a delay for the installation. At 8 am the next morning, I got a message saying that we were back on for 11-2. At 1:45 I get the new message saying they are going to be late and to reschedule. I get back to the office, and an hour later, I receive an email stating that they were incorrect and cannot service the building. WTH? Then why even pretend to send someone out and make me waste 3 hours. I should have listened to the reviews.

We’ve had Quantum for about a year, about 6 months into the service we would randomly get download speeds of about 20mbps in different areas of the house. We tried upgrading our plan, adding 2 extra pods, using our own router and pods, and we’ve had their technicians come out and test things on 5 different occasions. Each tech (3 different people) would tell…
We’ve had Quantum for about a year, about 6 months into the service we would randomly get download speeds of about 20mbps in different areas of the house. We tried upgrading our plan, adding 2 extra pods, using our own router and pods, and we’ve had their technicians come out and test things on 5 different occasions. Each tech (3 different people) would tell us some new way to fix the issue, only for it to last a week or less before cutting out again. I’m not a fan of paying for a gig of service and receiving less than2% of what I’m paying for.
