Received call from an "Investigator Quinn" saying he needed me to call him back, it was VERY important! When I called he asked me if I had a Mercedes. I said NO and then began to ask questions of my own, ie., Are you a police officer? What jurisdiction am I reaching? Where are you located? What is the name of your company? Receiving no answers, I told him I wasn't answering any questions either. Then I hung up.
