A year and a half ago, I canceled one of my two Vonage VoIP lines and switched back to a Verizon land line. Yet, every month, despite my regular calls to Vonage, Vonage bills me for its non-existent service. And, every month, I call American Express, and American Express credits my account for the Vonage absurdity. I now understand why 'Vonage the Dog' (as per the 'Mad Money' man) has plummeted to two dollars and change from its offering price of 17.
