Used Vonage internet phone service for more than 10 years while I was AD USAF. I recently retired and came back to US. Cancelled the Vonage phone service. They charged me $150 for the device that I bought with my own money at Osan AB, ROK about 10 years ago at local retail store and another $270 for next year service charge. I complained to Vonage and received email from them. The email stated they will refund the money but they never did. My bank stopped the payments. Now they are charging me another $25 for returned check fee. I send them the email from the Vonage customer service. I am extremely upset with Vonage.
