This one has called me numerous times and never leaves a message.

Got 4 calls in the last 6 hours from this number.  No one is on the other end, the other end hangs up after a few seconds.  When called it doesn't pick up and says that the number doesn't exist.  It appears the contract is from Santa Monica, CA according to my phone

Called me twice this morning and never left a message.

I received calls today @ 12:51pm and another call @ 2:22pm.  No one is there when you answer the call and no messages are ever left.  I saw on another site that this number is calling because/due to some kind of virus.  It will not stop calling.  It has called me for about 3 weeks straight with the same thing.  No one there when you answer, and when you call back it stays "hello and welcome to verizon wireless the number you have reached has been changed/disconnected."  It is annoying, but the only options I have seen is to somehow (either by your phone or carrier) get it blocked.

again another call and no on there.
