SpectrumVoIP - The first honest advertisement from Spectrum VoIP

SpectrumVoIP

(75 reviews)

We worked with Reagan Cooper and converted our phones (one landline, one existing VOIP, and two…read moremobile) to one consolidated VOIP system. Reagan was helpful, friendly, and professional. Our new phones work great.

"One of the finest legal corporate scams I've ever experienced!"…read more Turn around and run toward literally any other VoIP provider. Ignore reviews of those who've just signed up because we've been stuck with Spectrum VoIP for 3 years and time reveals the truth. I would never recommend SpectrumVoIP to another business. What should have been simple phone service turned into a 60-month commitment involving a third-party finance company, confusing contract terms, multiple departments giving conflicting explanations, missing historical documents, cancellation instructions we never requested, and countless hours of our employees' time just trying to understand what we signed up for and what it would cost to leave. The icing on the cake? Our phones repeatedly show "No Service" while we're still paying for them. We've spent weeks emailing Billing, Cancellation, Customer Service, and others just trying to get straight answers. At one point we were told documents were attached to an email--they weren't. I clicked the link to view our own support ticket and was told I didn't have access. Business phone service should make running your business easier. This has done the opposite. Save yourself the headache. Choose a month-to-month VoIP provider with transparent pricing and no long-term finance arrangement. I wish we had. Would give this company -5 stars if I could. The photo below would be an honest accurate advertisement from Spectrum VoIP....

Was approached by a young man at my door offering services from Frontier by Verizon. I was severely…read moresceptical anything would transpire at all, period. Nonetheless the installer showed up nearly on time, completed his installation with pertinent and truthful information. Introductory 90 day started AFTER installation. Very pleased to have jumped quickly on offer because I received $50.00 gift card, I wasn't expecting, 2 months into it. No 2 year contract.

1/5 -- Extremely frustrating experience…read more My Frontier internet went down around 1 PM and has now been out for over 9 hours. I work from home, so this outage caused me to lose 4 hours of PTO and I may now have to drive into the office tomorrow because my service still isn't working. What makes this even more frustrating is the complete lack of accurate communication. I tried contacting support and waited forever without getting connected to anyone. I also tried their outage text service and received no useful response. Then, when I finally got Frontier's online outage checker to work, it told me "Outage resolved in your area" with a resolution time of 12:00 AM on August 20 -- even though my internet didn't go out until approximately 1 PM on August 20 and it is STILL not working. I understand that outages happen. What I don't understand is leaving customers without service for hours while providing inaccurate information and making it incredibly difficult to get an actual update or speak with someone. For a service that people rely on to work from home, this has been incredibly disappointing. Frontier needs to do a much better job communicating with customers during outages and providing accurate restoration information.
