********** "Uber" driver

We were ****med by someone who sent an "Uber" driver to collect the phone we sold him. Pop and sms looked real legit, if the "Uber" driver didn't phone me to tell me this was a **** I wouldn't have known. He is *********ing us requesting R800 which was supposedly his fee or he will take the phone to the nearest pawn shop. His number is ***. Won't give me his location or name and cannot verify he is an Uber driver. Currently can't get hold of Uber to assist and CCTV camera footage for a registration number.
