staff members harassing students

I have been with richfield for quiet some time now. I'm very satisfied with the way they tutor and their work. however my problem is with some of the staff members at the BEMS branch in Bloemfontein. we feel uncomfortable and unsafe on the school premises as some individuals harass us ***ually at the campus. this leads to us missing lecture and affects our studying badly if this matter can be addressed i would be very happy
