Then he declines the offer and some how was able to make me send a offer to a alt account that seemed to be exactly same as the account i sent the offer to and i though i accepted the trade offer i originally sent but it was the offer that he sent me which was my unusual hat for nothing. then he just took my unusual with nothing in return.
