Campus Manager insulted me

I'm a part-time N5 student at a College of Cape Town( Crawford Campus), Last night the 26/02/2015 I attended my class as usual then after class I went to the Campus Manager's office (Mr Bowler) to give him the documents he requested from me in order to be registered for this semester as he said he cannot register me because he does not have my original documents so yesterday I went to give him those documents. As I walked in his office he said to me he does not want to see me, as I was busy trying to explain to him that I brought the documents he requested he started insulting me. He said ' **** I told you I don't want to see any students, you stupid idiot get out of my office, Im locking up\ he then continued swearing at me in Afrikaans of which I didn't understand what he was saying and he slam the office trellidor in my face.<br> <br> I don't know what I did to him that made him to insult me
