registration issues and lack of response

I have tried to register for subjects mng3701 and fin3701 but due to a system error it did not allow me to register for these 2 subjects. After numerous emails to *** visits to the port elizabeth branch and countless attempts of a phone call i still have no response. I need these 2 subjects to graduate and i cannot do it next year because of futureo work commitments. Unisa obviously doesn't want their students to prosper and graduate. Pathetic service for a academic institute. What happened to building a better future
