Dangerous driving by Courierit Drivers

One of your delivery trucks pushed me off the highway on the R300 close to the N1 exit inbound to Cape Town @16h20 today. I called to report the driver but manager not available, I was driving fast in the fast lane and wanted to change lanes to take the exit, as I was waiting for a car to pass with my indicator on he proceed to push me out of the fast lane with nowhere to go passing me in the right emergency lane almost causing a high speed crash in peak traffic, after that he proceeded to pass in front of me in the new lane to also take the exit, and then drove dangerously close to the next car, just a note, dont hire taxi drivers to do your deliveries, it reflects badly on your business
