Who called from 7188873973

REceived a call on my cell phone. No one answered after I said hello.

Received a call at home from 718-887-3973, but no one was on the line even though I waited for about 30 seconds.

Have received several messages from this number and they are looking for a specific person. They have left me messages. I am not the person they are looking for. I finally called them back and the woman who is english challenged did say they would remove my number from their information

call from 718-887-3973 came up as "Private Caller" on my caller ID.  A clever trick to get me to answer?  If so, it didn't work.  I didn't, and checked here, and was glad I hadn't.

Got a call from 718-887-3973; caller ID came up as "Private Number".  Silence on the other end of the line.  Is this just a way to see if a phone number is valid?  At any rate, it's a bother.
