Sellers BEWARE-

Someone purchased brand new Valentino shoes from me here on Poshmark. When they received they complained Because the box was not included. In my opinion - they wore them for an event/party and then returned them! I am shocked Poshmark sided with the buyer. Has anybody been in a position like this ??! Because I personally think it's fair and I have purchased shoes and other items on here without original box and it's not a big deal to m e.. thoughts??
