not taking back damaged goods

Every time I go into a Jet store I am disappointed, you always find numerous staff members hanging around in the store and only one cashier. Then after your lomg wait in the queue you finally get to the front just to have the cashier tell you they refuse to take back your damaged goods without a slip even though you still have the price tag.<br> <br> I bought a set of baby pants about 2 weeks ago. After opening and washing it I realised that one of the pants had a default, the one leg was much shorter than the other. Before i could return it my cleaning lady threw out the slip but I managed to retrieve the price tag. Today when I returned the pants the cashier refused to take it back without the slip. I have taken goods back to numerous stores without a slip only a price tag and they happily exchanged it for me. I am utterly disappointed and rather furious that i must pay the price for something that should not have been on your shelves in the first place. Needless to say i left the pants there because i have no use forit
