Siemens — DRIVING

I was driving along on the way home from brands hatch with my friend mark on the m25 when two of your employees entered the m25 at junction 30 I was driving the 3rd lane , they were driving eraticly and pulled straight into my lane causing me to brake to let them in, i flashed the headlights and the driver slammed the brakes on causing me to slam on my brakes even harder my cargo being my motorcycle and my friends motorcycle were damaged. I have not been able to get pictures yet but im not sure whether to report it to the police ? the details of the driver of the vehicle bg61 zmo was the driver that slammed on his brakes then disgused himself with a mask, the other driver was yf61 kdv.
