These idiots called with an "announcement" (caller id). We have family near Detroit, otherwise we would not have answered. They wanted to sell an alternative natural gas source not regulated by the MPSC. They offer a very low rate in the beginning and then raise it very high for the rest of the winter, and you're stuck paying it because they are NOT regulated. Several of these scam-marketers will take any form of "yes" that you might say to them and use it to bind you into a contract that you don't know about. We hung up without dignifying their call. The number is now blocked.
