I also had a problem, I call the call centre and they confirmed that there was a problem at 15.00 which they then fixed. Itold them that I was trying from 19.00 until 23.30 and still got error messages.
Only submitted successfully this morning. If any of you have the same experience:
- stick screenshot of failure in the assignment with a note to lecturer
- send an email explaining to :
myUnisaHelp@unisa.ac.za and
bugmaster@unisa.ac.za
Call centre told me that I was the only one phoning to complain so pile up those complaints......
