I answered the call from this number, after they had called several times & left no message.  The man said he was from "Santana" the supplier of gas for the past several years for Consumers Energy and because we had such a good payment history they were going to reduce our gas rate from over $1.00 which it currently is to $.71.  He wanted me to get an old bill & give him information from it over the phone so they could switch our rate.  He said there is no charge for this, they were doing it because of our good payment history.  I refused & asked him to send me information about the offer in writing, then I would consider it.  He agreed & said the Customer Service 800 number would be provided in that mailing & I could call & sign up after I received the mailing.  

We'll see if it comes.  Right now I nothing about Santana....
