Disappointed parent

I am very disappointed with the registration process at DUT. My son is doing final year in Tourism management, he tried to register the only subject that is missing so that he can finish his diploma but the system doesn't allow him to register. He is been going up and down the the campus and they keep on saying they will inform him once the system in sorted. Now I understand why there is so much of students committing suicide in DUT. I trusted the institution but it is now a shame
