got a call no message was left who is it?

stop

I keep getting calls from this number. When I answer, nobody says anything & the call will last for about thirteen seconds. I called the number back a few weeks ago. An Everest Institute employee answered and told me that he didn't know of anyone that would be calling me from that number. It's rather obnoxious and strange.

Just called on my work number.  Did not answer and no message left.

No more calls please
