keep calling - won't leave any message.............who are these  people, if they have good intentions, they should leave a short message and tell us who they are...................

I did not recognize this number that came up on my caller id called today so i did not answer. They left no message.

If anyone or any company really needs to speak with you they would leave a message.

Because I have a blocking device on my home phone i tried to call the number back and only got a recording stating that the number that I was trying to dial was of an incorrect code ?
Probably just another solicitation call which typically leads to some type of scam.

I, too am getting calls from this number and have traced it to the L.A. area code. However, when trying to call back, the call is interrupted by a message saying it is the wrong code. How do they do that?

When they call....it's just silence. No one to request for them not to call.  It's frustrating!!
