EXAMS AHEAD NO BOOKS R12 000 LATER

I have payed in full to do a course via correspondence through Damelin. I have payed over R 12 000. I was supposed to receive my study material on the 26th of March I called on the 30th and 31st of March to find out where it is, after 2 hours on the line holding on and extremely rude consultants I was told there are no books for this subject. May I just indicate that this is more than a month after I had payed and enrolled for the course and not once has anyone informed me of this. My firsTWO EXAMS are at the beginning of MAY. I will have to postpone and this will cost me extra time and money app R500 to do so. I am absoulutely APPAULED by the service I have received. I have tried to get hold of numerous managers but there are constant excuses. It is disgusting especially after they have received full payment on my behalf.
