Another SCAM. This time, surprisingly, they did leave a message. It was a robo-generated voice saying "You have been approved for a loan of up to $50K. SO.....(and some other things I ignored after I started laughing with the SO part put in there). No company name given in the message, just to a call back number if interested.
Stupid people don't even know to wait for the beep of the answering machine before leaving message. Have no clue who it is or what they want! Unsolicited robocall
