"Curious, the CSR can't tell me how many minutes I've used this month."
That's because they use the same web interface. About a year ago I came back from a weekend trip and needed to turn my call forwarding off. The web interface was down, so I called Vonage support to ask them to turn it off for me. "I can't", the agent said, "the web page is down for us too when it's down for you."
