poor service delivery - no response to long term query

I received an email fro m Unisa stating that my qualification is complete and i am eligible to graduate. in that time i had paid fees late and was made to pay an additional R1310. i had re-registered because i had thought i had failed... now i am trying to get someone there, anyone to clarify what my current status is... i have been calling for weeks and no one answers... emailing everyday and only getting back case numbers but no actual answer... this is beyond frustrating. i am extremely disappointed in unisa's management and staff as a whole... Poor service does not begin to describe what i have experienced... i am horrified at this level of poor service and complete disregard to another human being.... Private education is expensive but it seems the only route to take as 'SA's leading distance education provider"is failing its students miserably!
