Query: Few pages torn off and CD is missing. Seller did not notify customers.

I decided to buy this book because it's price was $8 less than the bookstore. But it was not worth it. This book should come with a CD but I found it's missing when I received the item. I had to copy from my classmate's CD. The seller put the condition as 'good' but the book is almost falling apart. Several pages were torn off, making it very difficult to read and carry around.
