Who called from 8505837873

Called at 10:15 this morning.  I did not answer, caller left no message.  There are too many of these jerks with phones to block every one of them, so I just didn't answer, as usual.

850-583-7873 called. I did not answer. They hung up as soon as answering machine came on.

Was checking Facebook on my cell, it started ringing.  Don't recognize # so didn't answer.  They didn't leave a message.  A few minutes later, phone rings again, same number and again no message.

Received call from this #, I answered, said Hello multiple times but there was just dead silence on the other end. Blocked the #.
