Mancosa not wanting to take accountability.

On the 6th of August last year I was writing an exam on the Mancosa page when it through me out on the last our of the exam, I tried logging back on and It gave me an error saying "Please note that you opened an OSA in another window. Please continue with your exam active window". There was no active window as I restarted the system all together. I called the student support line and they told me to wait as they are still waiting for response from their IT department until I ran out of airtime. I waited for a minutes hoping they would call back and no one did, i then had to buy airtime again and called them back, only for the lady to tell to just write what I could in the 47 minutes. I told her that it was impossible to write an 8 hour exam in less than an hour and she insisted that I write and submit what I could, I then wrote and submitted only 2 questions out of the entire exam and please note that i was now under panic.
