Who called from 3027561847

Someone answered wanting to talk to the home owner and I asked why they hung up

Two calls within one hour and no one on line. This repeats daily during the same time period.

Multiple calls, never leaves message, classic spammer/telemarketer symptoms. If you dial this number back you get a recorded message that "all lines are busy". Block the number.

Criminals for sure.

They called.  I did not recognize the number so didn't pick up.  No voice mail message left. I can only assume spam.
