unable to resolve conflicts

I'm so appalled at the way Lungani, The manager of steers handled an incident that took place at the steers that he's in charge of. He did not know how to calm down a situation that really got out of hand and that resulted with my phone's screen been shattered and my sun glasses being broken. My hand bag was shoved off a counter and he picked it up and placed it back on the counter and the guy that I was in a quarrel with pushed it again in front of Lungani and he said nothing to reprimand the guy for man handling my property. When everything had died down and the guys had collected their order, they attacked me using vile language and Lungani re appeared and when I was talking to him about the mater he blatantly told me he doesn't care that I was attacked. he said in Zulu, 'uhlanganaphi' which basically means me being attacked has got nothing to do with him and he doesn't care. what he said was utterly wrong as I was in a store he was managing at the time all of this happened. I felt so unsafe and angry at the manner he handled the matter. this was all just because the guys were not in the Queue and my friend and joined the queue and the guys said we skipped the queue.
