Bests & Worsts Reviews from Amazon

Whatever pleasure I derived in reading this book was ruined when I found out that, although I paid for an entire book, I only got 67% of a book. The last 33% was used by adding 2 books previously published by this author. One book I have already read, and paid for, the other I didn't want to read. I rechecked the description of this book on Amazon but couldn't find anything that indicated this was not a complete book. I didn't get an ARC, I paid full price. I want my money back and want this author to stop this deceptive practice.
