Who called from 7812572547

Called at 8:20 am on a Saturday left no message.

Same as Anne. Called at 8:22 am. No message. Third or fourth time. Sick of all of them.

Caller ID Lincoln left no message.  Why call  Robo?  Scam?

Dude called and asked for someone named Greg. Said I think he has the wrong number and kept insisting he had the "right number but the wrong name" and kept asking for "my parents" in an aggressive tone

Probably a scamming agency

Just called my house with this number on a Sunday.  Caller ID said "Local Call Area", but the area code (781) is no one I know so I didn't answer and they left no message.
