Worst experience with a service. VOIP set up is not user friendly. A great deal of time and phone calls were spent on issues. Each service seems to have a different department and different person to speak with. Service was not worth length of time it takes for them to set up the dashboard, the time I had to dedicate to do the setup configuration, the countless time I have been on hold or had to talk to representatives, and the quality/reliability of the calls. Cancellation of VOIP has been a nightmare. My VOIP account was renewed after I received cancellation confirmation. I was furious after the numerous time and phone calls it took to actually get the cancellation confirmed. The excuse was that they had to migrate fax history since I was keeping my fax number. For a company that handles large businesses, the fact that they cannot transfer a fax history timely is concerning. I will be cancelling the fax service as soon as the VOIP issue is resolved and "finally cancelled". I wish I could bill them for the hours I have wasted with the countless phone calls with them. Stay away from Nextiva and save yourself a lot of wasted time and frustration.
