Query: The book has almost 100 pages missing

I contacted Amazon.com to let them know that this book (the 4th edition) has almost 100 missing pages (all the appendixes). The book was replaced by another one with the same number of missing pages. I tried to contact the publisher (Wiley-Blackwell), and they make you enter your life story just to email them. The book presents great information, but unfortunately, it is a rip-off because the most important information is missing. DO NOT BUY THIS BOOK! RIP-OFF ALERT!
