Instruct: Classify Amazon reviews into positive or negative sentiment
Query: seller dishonest

Well, it turned out that I really didn't need this product and it took me a long time to figure out how it worked. I gave the seller a mediocre review because I didn't think I could return it. He then contacted me and told me to return it for a full refund. (He also wanted to me change my earlier review.) I returned it, did what he instructed and now he won't give me a refund. Won't respond to my emails either.Save your money....
