Terrible Service and Company policies for Miladys

I bought a pajama from miladys lenasia on Tuesday 12/05/2015 i have subsequently misplaced the receipt but used my card i have shown them the proof that i bought it and used my card and they refuse to assist in the return of the garment. i called the head office where a very unhelpful Charnay claims that at 1:45pm on the 15/05/2015 there is no one that can assist me or speak to me in senior management and there is absolutely nothing they can do to assist. That is terrible service for this day and age all other chain stores can assist but Not Miladys!!
