Magicjack: Technical Issues From Day 1

Had technical issues from day 1.   Spent literally over 15 hours on their online chat tech support.  Tried every software & driver re-install, and configuration possible.  Ended up giving them remote access to my machine, where they added configurations to my internet router, and my firewall.   Still did not fix the problem after 15 hours of working with tech support.  At that time, they started dropping my chat session for tech support.  I would contact them via chat, they would say they are transferring me to an agent that can help me, and that was it - the chat session was dropped.  Tried that a dozen times before I finally just gave up.  At that point it was apparent they did not want to work with me on resolving the technical issue.  I've been a technology professional for over 20 yrs, and owned a software company.  That was the most horrid technology experience in my lifetime.  I had no choice but to go with another provider.
