telling them exactly why this wasn't a good idea...

Its also possible to contribute a review for this book on Amazon, and to contact Amazon directly to urge them to take the book off sale:
http://www.amazon.co.uk/email
Click on 'Express' and then 'My question is not related to an order'.
There is a freephone number to call too:0800 279 6620
Suggesting that you won't buy anything from them while they continue to sell this book might concentrate their minds.
