Unhappy student

I really love Mancosa but I am having trouble with their lecturers and whoever marks their papers. A couple of students and myself worked together on a project together because we are all first time students on this course, let alone cost budget management. We got very bad marks for plagiarism even though we did not copy and worked together on teams. Then the same person who marked our projects has the nerve to leave comments that read "EXCELLENT, WELL DONE!'' as if to purposefully mock us, who does something like that? If we knew everything we wouldn't be applying for studies nor would we be working together. I am very disappointed , if its not incomplete lectures its insults from the people that mark our projects and we get penalised for things that dont make sense....
