Query: Very displeasing!!

I was very unhappy with this product. I ordered this book on January 7, 2010 the current date it February 11, 2010 and I have not got my book in the mail!!!! I do not plan on buying products from Amazon any more when they lose the products that I have purchased, it is not right for them to make a profit off of me when I do not receive what I paid for!!!!
