Unisa student/3G prepaid data bundle not activated

I purchased the Unisa3G prepaid data bundle from Unisa about two months ago.<br> This is supposed to be month to month for 6months however I did not receive my data for this latest month.<br> i usually receive the data on 29th of each month.<br> i have phoned the callcentre (082155) 4 times today and none of these operators knew what im talking about, infact they couldnt help me at all and kept putting me on hold .<br> I am extremely frustrated as I need to use the data to submit and do assignments and now i am unable to function.<br>
