Scam. Even if it's a legit energy company what they do is bait and switch. They sign you up for say a year. They say if you don't like it you can cancel. The rate is low compared to your other supplier. Then surprise a couple months later the rate is double the original supplier. You can cancel but there's like a 400 cancel fee. So you either pay the fee or pay double electric bills for the rest of the contract.

So even if it's not an illegal scam, it's still a con to screw you out of money legally.
