Very expensive phone calls

I made some phone calls recently. Probably around 5 or 6. Most were local; maybe 2 were to DC. A few minutes each. They cost me about $40 each.

A few months ago, I signed up for SunRocket, the VoiP provider. I decided to take the option to prepay for the year. And now they are out of business! I doubt I am getting that money back.
