Query: I did not receive this book I have sent Email and seller will not reply!

I paid good money for this book and did not receive it from seller I would not buy from them again! They will not respond to E-mail and I cannot find a phone number for them! I can not find a number for Amazon either on their web page! I hope that I might still receive the book! I just can't give a reveiw for a book I did not receive! I had to give it one star or I could not post this!
