I too have been ripped off by Vonage. I cancelled my service and had to pay for 2 lines of cancellations of $39.99, and also the equipment for $79.99.
I don't want it, but they won't take it back. One phone line was a $24.99 rate, the other a $14.99. But yet I pay the $39.99 for each one. Even though the service was less than perfect.
Did not work most the time, not compatiable with my internet service at all! When you cancel they harass you to remain a customer. The response team leaves messages for me to call them back, but can never get through. We have been playing phone tag for a week now.
I do work, and cannot be home the hours they are availiable, not sure why they cannot handle it via email!
At any rate, I am still trying to get a hold of the response person!
