Pick n Pay Drive does not stop at stop sign

One of your small truck delivery trucks just turned in from a stop street onto on coming traffic without stopping. I could not break in time to stop and he tried to keep on driving away, and I had to chace him down hooting. In Douglasdale just after Glenluce and before the small pick n pay off Douglas Road. He would not give me his ID - his registration is: CN71LBGP. I have a photo of the driver and the passanger in a chef jacket who also had a pick n pay jacket. I was driving with my mother who is a witness to him not stopping ! This man was arguing with me, and there is no argument to him not coming to a complete stop when joiing a road with free running traffic! He is rude and a ****. His passanger thought this was all funny and smerking! But this is disgusting and ruining people days and I am just glad my children were not in the car with me! Does this man even have a drivers licence! I will be taking this further with my insurance and the police!
