Three case numbers later and still no registration

I tried to register for the academic year 2013 on 19 December 2012. For some reason the online registration would not be allowed and I was told to send a query to the study-info - this was done and a manual registration form was received the same day.
I completed the necessary form, emailed and faxed the same through again the same day with proof of payment for registration.
Registrations for the new year closes today, and I still have not been registered despite three queries and cases loaded since?
Please would someone contact me to sort this out or make sure that you refund me immediately!
Case numbers 12354NX28265 and 12348NX14628
