Scandalous neglect of a PhD student

I used to love this university. Since my first year undergrad in 2006, I've been a proud student... but now since 2015, when I registered for my PhD in pharmacy, it's been downhill and catastrophic. I haven't had any assistance nor adequately supervision through out. I had a cosupervisor who resigned without even telling me. Then my actual supervisor who hasnt sent me one single correction in 4 years until I was handing in, also resigns. The HOD resigned and the whole department is a mess. I pay high fees and obtain zero education. Its scandalous and I want a refund. My proposal had a budget of R40k was approved and the 'research fund' was to cover it. Now in August, after zero funding, I fended for myself and managed to submit a less than fantastic thesis. Nevertheless worth at least 50%. So I submit to exams office and 6 weeks later, check the progress of my assessment. To my great surprise they say it's still laying there in the office. Hasn't been sent to panel corrected let alone corrected and marked. What is wrong with this picture??? Too much to mention. The international office hasnt helped. The pharmacy department isn't helping and now I've emailed everyone I could, and now what's left is to sue them.
