very unhappy with the institute

I app**** to unisa during their application period last year in august 2015 for admission this year. to date I have no feedback regarding whether I have accepted or not. the service is pathetic. I am in Durban and somehow I cannot get hold of the Durban branch. I have phoned the joburg branch from last Monday, only to be told that their systems are down and I must call the next day, when I do they are not able to help me, the last I was told that I should go to the branch, I work week days, how can I take off. the registrations are open and they are even delivering study material. please assist
