These guys ripped us off pretty good in Ann Arbor Michigan. They said they would save us a little money and it was free to sign up. They charged us almost 4 times the DTE rate in Feb and are about 25% higher in May of 2014. I saw that I had large bills over the winter and just assumed I was using a lot of extra energy due to the extreme cold we were experiencing. Nope, Volunteer Energy pricing was at the level of criminal.
