"This is Mrs. Peterson I've been trying to reach you regarding an important matter about the supply charges on your National Grid electric account." This number is fake, and the call back is a different number 1-413-241-5347. They are basically scammers trying to get your information so they can reduce your rate? Uh, huh......

Same thing here. Called back only to receive recording asking you to press 1 if you wish to be placed on the DNC.
Legitimate Companies would identify themselves, which leaves one to speculate and conclude that this "operation " is s scam.
Add to your blocked list. Then tomorrow, these criminals will spoof yet another # and call you again and again.
I so wish somebody could prosecute these thugs!
