Unisa , no feedback , moving of goals , poor management

I have completed my studies with 480 credits and 40 subjects , after finishing a F1 concession task unisa send to me in order for me to be assessed as final year student , unisa advised me that some of their modules changed during the years of my studies and that the guidelines i followed ( provided to me by unisa ) is not complete , now i have enough credits and subjects , Unisa wants me to do 3 additional subjects before my qualification can be sent to me , i was awaiting me qualification status and while im waiting missed the oppertunity to write those exams Unisa failed to contact me in time resulting in my year to be rolled over to 2021 to get my results
