One of the most frustrating situations is when you have been nailed by some company and just don't know what to do about it. The fact is that if you know the simple skill of writing the complaint letter, you can save a lot of frustration and time.
In this book, you learn how to draft your position such that it's a convincing plea for them to make it right rather than ignore you. Venting may be satisfying, but not productive. Getting a lawyer is costly and often isn't necessary.
The main reason I like this book is that I've already discovered some of the techniques in here, but there's several I didn't know. This book is full of actual letters he's written as well as the exact results. Benefit from his experiences and see some results with a minimum amount of your time and attention.
