It's a "company" called Premier Energy. When a number like this calls, I quickly pick up the phone, then disconnect. I then call the number back to see what happens. In this case I got an answer that said "Thank you for calling Premier Energy. If you know your party's extension, please enter it now. Otherwise, push "0" to connect to an operator." I didn't bother to do either, so I don't know what the result would be. If they call again, I will try to speak to someone to get information, & will report back.
