Query: Bad Seller, Good Book

The book is pretty informational and it I like, but the seller advertised a new book and the book wasn't new. The book was old and had pencil markings in it. I contacted the seller because I was upset, I didn't pay for an old book, I payed for a new one. Well he was no help and I ended up fileing a claim. Then he contacted me after. Every email, except 2 out of the 5 he sent since the first time I contacted him about the problem, was insulting to my grammar and he talked to me like I was a child and he a college grad from Harvard. The only reason 2 were not so insulting is because he wanted the book back so he tried to talk a little nicer. Well the fault falls on the seller in this case because if you sell anything you always check the condition of the product before you sell it. If it is not as you say it is, where I come from that is false advertisement. So the book is a nice read but the seller I won't buy from again. That's sure.
