No message. Nothing. Anyone else?

Yes...I, too, have been getting calls from this phone #.  They have been calling every day and my caller ID shows the phone # only.

Say Verizon in bound sales.  

This fool calls all the time. Caller ID unknown, when you pick up the line they hang up. What gives?

they call every day and night never leave a message they just hang up when they hear my voice message. I pay for unlisted number, but I still get this call.  this has been going on for months now.  they are very annoying. thank god for caller I.D. I never pick up people I do not know. this should be reported or tracked down.   who are these people.
