WD Hearn Machine Tools - Reckless Driver

I wish I could share photos or even a video of this company's driver who drove extremely reckless and could have caused me personal injuries and damage to one or more vehicles. On 26 May 2023, I was driving down Christian Avenue in Epping, a Driver from WD Hearn Machine Tools with vehicle registration number: CY 46424 abruptly braked in front of me, without using any indicators. I almost drove into him, then into oncoming traffic when trying to pass the driver. When the oncoming vehicle passed, he made a U-turn in front of me, and parked on the pavement at the right hand side of the road. I parked and went to tell him that he has to take better care while operating a motor vehicle. Before I could say anything, the driver started behaving erratically and childish, taunting me with being a "Karin". I thought him to be under the influence, as I started to get concerned for my safety. I phoned the company to report the driver and they asked me if there was an accident or not. I responded by saying he clearly endangered me and other drivers. Need there be an accident and dire consequences before they address his dangerous driving. The manager just laughed at me, explaining he does not know what the problem is because nobody got hurt. I believe it to be absurd and I took personal offence getting laughed at. My wish is for this review to be shared and individuals would rather do business with a company who contributes to the safety and respect every road user deserves.
