I got a response from the Maine Governor's Office on Energy. Word to everyone who lives in Maine: You are not protected from price gouging.
The only protected customers are those who receive governmental assistance for heating costs. And here, the protection is only this: If you are out of the fuel needed to heat your house, a company must deliver to you. The company has a right to charge whatever they want.
I received a reply from "my" government saying "I understand your frustration." Oh sure. I am not frustrated, sir, I am angry.
