Venue Change at Unisa without Student’s consent

They change students venue without informing them properly . They just sent an email stating that unisa florida is full. I will write my exam at Randburg . And i can’t change it, why didn’t they state this before , when I was registering that I’m going to write my exam at this centre if it’s full , they just said that they will change my venue without my opinion to write my exams there I am a first year student and I am not fami**** with these things. Now i feel like i wasted my money by registering at unisa and they don’t even offer transport. I don’t have a car am using public transport. So how am i gonna get to randburg because i only budgeted for florida not Randburg. And when you get to the exam centre late they won’t even want to here your story. The people who decide on things like this are depriving people like me education. And wasting their money as well.
