Who called from 2690002828

I got a call from this number at about 2:45 PM.  It was not a foreign person, and the number was from an area code in my state.
Him: "May I speak to the person who takes care of the Michigan gas and utilities bill."
Me: "What do you want?"
him: "I'd like to speak to the person who takes care of the Michigan gas and utilities bill."
Me: "Yes, you already said that, but why?"
him: "is your address ***--------***?"
Me: "It is."  (I wish I hadn't confirmed this)
him: "Are you the person who takes care of the Michigan gas and utilities bill?"
Me: "We don't use that service." (again, I wish I hadn't given him any info whatsoever.)
him: "Ok, I guess I must have the wrong number."
Sounds fishy, fishy, fishy and when I tried to call back, there was a Verizon message that said I had dialed the number incorrectly, but I did not.

Called 3 times yesterday and once today (already). Hangs up every time.

called and left no message or identifiction. Must be a robo call.

Has called once a day for three days running. No message left. I don't answer numbers that I don't recognize. If it's important, they'll leave a message. It's going into my Call Block list now.

Want to know if I was responable for the Michigan Natural Gas Bill, she hung up when I said didn't have Natural Gas.
