Repeatedly getting calls from 347-821-4818 this has to STOP!!!!

I keep getting calls from the 347 area code.  When I pick up, they sometimes hang up or say some nonsense.  They call all hours of the day.

Got a call tonight.  Didn't answer.

I got a call from this number today.  No one was on the line.  I waited for a full minute, but no one answered.

Pretty annoying.

A female kept asking for someone who wasn't here in a VERY nasty officious manner. Refused to identify self after being asked 3 times. Finally said "I am from an organization which Mr._________ supports. And when told AGAIN the person was not here, she said "I will call back another time." and hung up. Rudely.
