Universal Energy?

I think I have just been scammed by Universal Energy. We let them in, we signed, and I said after "I don't think it was the same company we were dealing with". This happened two weeks ago. I didn't give it a though until today when they phoned to confirm stuff, and then they said the other company may charge a cancellation fee. I said "we thought you were the same company". Then I looked online and there are write ups about scams and stuff. Oh dear.
