Express way to an accident

Yesterday, the driver of an MTE Xpress vehicle travelling down Koeberg Rd towards the suburb of Tableview did not wait his turn and merge into the lane as per etiquette and road rules. Instead, in bumper to bumper traffic and in the rain, he insisted on forcing his way on the left hand side of y car and push his way into the lane. At first I stood my ground, and his not yield as I am not required to, but he continued to force his way into the lane without an indicator in an aggressive manner, almost causing an accident and serious damage to my car. I had passengers as well as my 12 yr old daughter in the car. We took photos of the vehicle and have dash cam footage, as well as witnesses. I called the company and reported this incident. I am appalled at the manner in which this driver acted. He happened to drive almost to my home road and when I stopped and asked him why he drove in this dangerous manner he ignored me and carried on collecting parcels, all while the next client he was collecting from laughed their heads off. Disgusting behaviour, I will be laying a case of reckless endangerment on the road this morning.
