Calls 2-3X a week and hangs up without leaving a message. Hope this stops soon!

Calls almost everyday, never leave a message.

This number call and hang up
Then again a man said hello and hang up
Then again a woman call asking to buy a property ?
No property I own so I said which one and they had an address  if they in Bayone  why they want to get a Paramus address  
I also ask if she was a realtor she said sister so so  then I hang up they didn't call back

Yes they call all the time no message , I think its a cold call real estate scam looking for listings
