Driver is Aggressive and Dangerous

On Saturday the 18th of April 2015 at approximately 11:30 am, I pulled out of a driveway around the corner at the airport only to hear a motor vehicle spinning and racing around a corner not far me, I slammed on brakes and saw this guy come racing towards me almost smashing into the side of my car (which had my brother and my two young sons in it), I ask made the gesture ask what the hell. the driver Jason Samery then stopped his (First car Rentals) Renault Sandero and started threatening me and shouting saying it was his road i and should F*&k off. I told him I would report his behavior and he said go for it. I went to their office at the Airport and told Jacki (The Manager on Duty) what happened and we went into the parking area to chat to this guy (Jason Samery), whilst walking down he came racing towards almost running me over and stopped, if I had not jumped out of the way he would have ran me over. Jacki saw this and shouted for him to stop. I want some answers from this guy and First Car rentals on what they are doing about him, he should not be allowed to drive a vehicle with that sort of temper. I have laid a complaint with SAPS.
