Angry Student!!!!!!

I app**** for ECD at the university in 2020 just before the lockdown. When I finally received my study materials it was not all there. I communicated with the university about it and was told that I won't receive any assistance since people are working from home. I understood that at the time because it was during level 5 lockdown and there was nothing anyone could do to assist. As the restrictions were eased and people were going back to work, I still didn't get any assistance which I followed up on through email. As time went seeing that I didn't get any help and schools were opening up again I went to the university and found that everyone from the faculty is still working from home, and took details of who to communicate with from the note that was pasted on the door at the university. I finally got details of the professor in the faculty and was asked to forward all communication I had which was about 40 email conversations. Since then it's been quite. I then asked for my money back which is about R5000+ that I paid for because I am tired of being sent from pillar to post and I was told that I need to register again. How does resolve this issue at hand with such a big university? I urgently need assistance from someone who knows what I need to do next and where to go to for help.
