Appears to be a telemarketing can for a secondary natural gas service. Consumers Energy would still provide the gas, this company would just make money for the "service". They often give a great rate up front, but due to requirement for a contract, you'll end up paying more over the length of the contract.
Declined call no message was left, I used two spy dialers to call back with no answer. Verizon flagged the caller as Potential Spam. I blocked my number and this was played: We’re sorry the number you dialed has been disconnect or is no longer in service please check the number and dial again 14c
As noted above, it's a private number. Of course, because it is a scammer.
