I got a call but didn't answer. No one left a message.

Why is it necessare for some jerk to all and not leave a message and then tell you, you have been spamed.  The nerve of some people.  They need to be shot.  Have half a brain to call someone and tell them such thing.  

got a call claiming to be selling security systems from a Julie Burch at 9379401436
caller id said it was a cell phone
