EXAM VENUE CHANGE!

I registered for the first semester and have always written all my exams in Durban Ntuzuma B centre and all of a sudden it has been changed to Durban Hellenic Centre. No one has communicated with me with regards to exam change, and after send ing an email i am being told that its due to exam centre capacity. this is unacceptable and would like this to be changed back to my original exam venue.. HOW CAN YOU CHANGE AN EXAM VENUE, TWO WEEKS BEFORE THE EXAMS!!!!
