Query: Missing pages

I bought this book for an online course and was approaching the final few quizzes and essays at the end of the semester when I realized that this book had 50 pages that were printed twice and was missing 50 pages. Just so happens that I needed those missing pages to complete my course and was forced to purchase this book again. Did not have time to return and get another copy.
