I WANT TO REGISTER

I am trying to register online and I get an error response.<br> I have e-mailed and sent text messages and yet no one at UNISA is getting back to me.<br> Is this not suppose to be a distance learning institution where one can sort out their registration, especially if you a an active student?<br> I don not have time to go queue hence I chose an online institution <br> I have now missed out on a semester due to Unisa's incompetency.<br> <br> Who should I contact now?
