Who called from 8572553020

Person calls, once you answer the phone you hear the person talking to someone else and then hangs up.

Called, I asked who's calling, he said, "Uh, I don't know." and hung up.

keeps calling and i don't answer it but has called multiple times over the past several days

Called, asked for me by first name, he said "you have something hear" then hung up.

Keeps calling and hangs up after I say hello. I have never searched a number and actually found so many troubling complaints. I wonder what we all have in common. Who is this person? Are you all from MA like the number?
