Worst Service and systems ever

I have always experienced poor service from UNISA but this time they have crossed the line with their lack of response to enquiries regarding student registrations. I spent almost a month trying to get through to the registration department and when i did finally get hold of somebody telephonically i was passed around to different departments as nobody knew who was responsible for assisting with the nature of my query. This eventually resulted in me not being registered for the semester after having made follow up phone calls with the person who promised to provide me relevant feedback last week. I will be taking this up with the Department of Education as it is unacceptable that an institution of this kind lists telephone numbers on its website and yet there is never anybody there to answer the calls when students call. The phone just rings and there is no answer. I added an additional subject to my existing ones and paid the minimum required fee which was allocated incorrectly. Nobody could assist me even when i made a call to the Dean's office. They gave me a run around between the finance and registration division before removing my temporary registration from system.
