MODULES NOT REFLECTING

I have registered on the UNISA site to complete a qualification, made the payment and received confirmation that I have been successfully registered. After being registered I am NOT able to view any of my modules via the UNISA website. I have emailed and called on numerous occasions and no one seems to be able to help me?????? How am I suppose to commence my studies if I cannot see what I am registered for or the course work. I really NEED someone to have this matter resolved as I registered early in order to start my studies early. I really do not have the time to be messed around like this. YOUR URGENT ASSISTANCE IS REQUIRED!!!! I'm sure this is just a "system error" that needs to be fixed.
