I write this as a warning to consumers. The concept of having one's phone service cloud based is not only brilliant, it is very cost effective, unless you choose Vonage. It is no different working with them than any other major phone provider when it comes to incompetency, service issues and over-charging. Dare I say, maybe even worse!
Vonage has serious communication problems within their own organization. No one knows what someone else has done, how to speak with another department in their own company and therefore is 100% ineffective in getting anything accomplished.
I tried setting up multiple lines for business service. Started off with 2 of our numbers, which actually went fairly well but was then "quadruple" charged by Vonage. That was 2 month ago, and with the writing of this review, still have not received reimbursement despite speaking with their accounting department 3 times, customer service twice and 2 supervisors. And that's not even the worst part.
Vonage never took the right steps to transfer our other numbers. The details of all this would take too long to go into but suffice to say, I made 62 phones calls (yes, really, 62) in a period of 3.5 weeks to try to get to the bottom of the nightmare and ultimately cancelled the service altogether.
A great barometer when choosing any conglomerate to work with is that if they don't have telephone numbers to reach a headquarters or executive offices, then you know there are going to be problems. Vonage posts a number for executive offices but its not an executive office, its simply customer service.
They also give customers the ability to write a complaint on their site, which creates a case number to be responded to within 48 hours. Tried this and no one responded. False statements and misleading customers regarding pricing, service and complaints, on a company's website is illegal but they do not seem to mind!
I'll say it again, NOT WORTH IT. Choose another provider.
