Examination results

I started with this College in this year and I am a part-time student, I wrote my Bookkeeping examination and I couldn't see my results on the portal. On the 19th when I go to school to check I was told by Loyiso that I got a SUP and there were people who were writing supplementary exams on the 19th at 09:00 am apparently. When I ask why was I not contacted, NO SMS, NO CALL NOTHING!!!!! Apparently everyone in the HBK class had NO IDEA that they had to write!!!! When I call the college for Duncan the phone just rings and rings and rings... THIS IS NOT FAIR because a colleague of mine that also studies at ROSEBANK COLLEGE was called by in the week to say she must come and write a SUP. At this point I do not even trust the marks, I need them to Re Check my script and MARKS
