PAYING FOR STUDIES, NOT RECEIVING STUDY MATERIAL

I AM A STUDENT AT DAMELIN CORESPONDENCE COLLEGE. I HAVE NOT RECEIVED 7 OF MY 10 PRESCRIBED BOOKS THAT WERE PROMISED TO BE WITH ME BY THE 21ST OF DECEMBER 2014. I AM STILL WAITING TO RECEIVE BOOKS ALTHOUGH I CALL NEARLY EVERY DAY MULTIPLE TIMES AND SEND OUT EMAILS ENDLESSLY. THEY HAVE NOT DONE ANYTHING ABOUT THIS MATTER. AND THEIR FEEDBACK IS SIMPLY, \WE ARE ESCELATING YOUR QUERY"AN ESCALATED QUERY IS ANSWERED WITHIN 48 HOURS THEY TELL ME. EVERYTIME I CALL IN AND OF WHICH MY QUERY HAS BEEN ESCALATED MULTIPLE TIMES. YET NO FEED BACK HAS BEEN RECEIVED....<br> MY EXAMS ARE SET TO START IN APPROXIMATELY 11 WEEKS 2 AND A HALF MONTHS FROM NOW AND I STILL DONT HAVE MY STUDY MATERIAL. """
