Recieved call from this number at 11:00PM.  Recorded message said she was calling for Arizona Credit Union.  Hung up right away because it had scam written all over it: the hour called (financial instituions don't initiate outbound calls that late at night), the area code was not from Arizona (I live in AZ so I know all the AZ area codes), and I don't have any dealings with Arizona Credit Union (it doesn't exist).  Did some online research the next morning and found the number originated from the small town of Lamar, MO.
