Got one also, all numbers are blocked except contacts so all go to voice mail.

Called twice. No message. ID says Huntington Park, CA

Called Thursday, May 12, 2016, at 12:20 pm PDT.  Caller ID showed "Huntington Park CA".  They hung up before answering machine came on.

Called my office number at 7:53 pm.  Click to the boiler room and a meek woman said my name.  I barked "what?" and she hung up.  SO sick of being bothered by these idiots!

This is an INVALID phone number, and so are the callers!  I received a call from these idiots and the Caller ID says:  "Huntngtn Prk CA".  What idiots!  There is a Huntington Beach, Ca, but no Huntngtn Prk CA.  Do not even think about talking to these criminals, and that is exactly what they are.
