Received call & didn't recognize the area code and number. Let it go to my answering machine and wait to see who was calling. Nobody said anything. Picked up the receiver and asked who was there and got silence. Told caller never to call back. Blocked future calls as I suspect they will call again. Ny number is on the NDNCL, which is basically another useless federal agency who wastes tax dollars and doesn't do anything to stop these types of calls!!!!!!
