Marilyn Small from New Lenox, IL on October 6th, 2018
Someone messed up my order
On May 3 I went online and changed energy providers through illinois energy ratings.com. I received a confirmation e-mail and then, I have heard nothing. As a matter of fact, I received an e-mail on July 3 from Champion Energy, who had been my provider for the past few years, thanking me for renewing my contract with them. Someone dropped the ball and I don't know who, but it would appear my request for a new provider did not actually go through.
