We got the same call, with the same "reference number". That definitely tags it as bogus, since different people would have different reference numbers for their accounts.
I got the same call and VM. It sounded sketchy and I'm glad I googled. deff not calling this person back! I have a MA number but I live in NYC! I did recently switch energy providers (all sustainable energy now!!) so i was a bit curious if this was real. gotta love the power of the internet. Thanks everyone!
