Cannot complete online test as unisa wont load

Hi<br> <br> I was currently busy with a Unisa online test (industrial Psych 1601), the website kicked me out and will not reload or open again, My internet signal is excellent. Unisa only allows two attempts to do the test, i only managed to answer 5 out of 50 questions before their website kicked me out, I now have 1 attempt left and the website refuse to reload. Unisa has made it clear that no extensions will be made nor will the test be re-opened.<br> <br> I will now fail this test due to unisa's website overload.
