Person or persons continuously calling every day, do not leave messages, nor do they know the correct name or pronunciation of the person they are calling when I do answer and when questioned hang up.  Annoying.

Just received a call from this number and wondered who it was...and where.  646..New York.  M-m-m-m-m

This number has called my home a couple of times. The first time they stayed on line but would not answer. The second time they hung right up. It comes up a private name with the number. With all the luring and stealing from the elderly I am wondering.
