Hello, Nqobile -
Note: Fixya.com, a website intended for asking and answering questions on how to go about REPAIRING THINGS, has no affiliation with the University of South Africa (UNISA.)
I found a link for this information on the UNISA home page:
Intermittent unavailability of myUnisa
Due to unforeseen circumstances, myUnisa may be intermittently unavailable throughout today, Tuesday 17 April 2018.
Students with assignments due on Monday 13 April and Tuesday 14 April 2018 will still be given an opportunity to submit their assignments.
Our technical team is working on the problem. We apologise for any inconvenience this may cause.
This is the link to the Student Enquiries page for UNISA:
Look down that page for myUnisa & myLife. Use the telephone number listed there and call so you can talk with a person at the university who can assist you.
