Query: Beware of seller nathan dalton

Nathan Dalton sold us this product. Previously, I had bought several products from Amazon with great success. Nathan Dalton claimed one page would be missing. Eleven pages were missing from parts of two chapters, making the book useless as a class text, which we bought it for. Nathan Dalton would not respond to our request for money back. He is a liar and a con. Another review of him shows his arrogancy. He will sell you books with missing pages at full price. You won't get satisfaction from him. Buyer beware! I am considering filing a claim with the Better Business Bureau about this charlatan. He makes Amazon look bad.
