Exams Coming Up, Still waiting for Study Material

I registered in December last year, got all my study guides except for 1, Mac2601 Study Guide, part 1, I have sent emails to lectures about this issue and it is still unresolved, exams are around the corner and I am still waiting, I am tired of studying through PDF files, I demand the book I paid for, how can 1 book be out of stock from December???
