Got a call from them on Saturday morning.  The number was identified as the US Post Office.  They did not leave a message.
    It would seem someone either reacted before looking or just doesn't have caller ID before they posted a complaint.  What is the first person reporting this message actually speaking with the caller of this number or are the simply guessing.

   It does seem possible it really could be the USPS calling to simply say they have a package to pick up or some other postal-related activity, other than someone going postal, which would be really bad.

 I wonder if someone can claim to be a govt. agency without fear of reprisal or if the owner's of the posted number are really for the USPS...

Wish someone

714 is a California area code. I'm not expecting any packages from California and the California post office wouldn't be calling me here in NY to pick up a package

is definitely a scam ... caller id said USPS Garden Gro... not "United States Postal Service"
answered and recorded woman's voice starts talking about credit card account etc... didn't listen to the whole thing

yeah i got a call saying it was from the orange county area but i dont know anyone that kives in OC so i didnt answer. thanks fir the help!

Received a call on my cell phone from 714 894 5884, began with "There is no problem with your credit card but we can lower your rates". Listed as anonymous caller.
