UNISA Destroying My Future and Dreams!

I went to the Port Elizabeth UNISA centre to register for a module that I wanted to do to improve my average (the lady helping me could not understand that!). I was told I could not register as I have completed my degree and the system won't allow it. I find this absolutely unbelievable as there is a policy of redoing a module so I have no idea what she was telling me. I feel absolutely dejected and bitterly disappointed as I need to do a module again to improve my results so that I can apply for Masters. UNISA is at it again with its ****!!! Never mind the fact that I wasted my time, money and resources studying for 3 years for a one year Honours degree because I was cheated out of marks and failed in the examinations even though I had a very high year mark and practiced examination questions of which I was sure I was going to get distinctions. Way to go UNISA! I am finished and done with you people!!! There is no hope for this institution as it is getting worse each year!
