管理员，版主，你好，

i paid $29 for harry potter books posted by xiaoai ($20 for books and $9 for shipping), i paid first, but received a ipadpro keyboard case.

contacted "xiaoai", avoided my question, telling me about that she shipped a package, the point is "i paid for books, not your keyboard case", it is cheating. and i have no room to recycle non-useful stuff from others
