Poor customer service return policy needs changing

I feel utterly disappointed in clicks , I went in to your Atlantis Branch to exchange a Safeway Ionic Technology turbo power hair dryer I got as a gift. I explained I never used it as the consultant can clearly see it's brand new I explained what the problem is as well as telling them I got it as a gift. The way they went about this was upsetting because it wasn't a problem I cause it was a fault on the dryer. The consultant when to ask the manager of the store (Sanobia) and the manager had the nerve to tell the consultant to tell me that they can't exchange it without a slip. My problem with this is that I didn't ask for Money back it wasn't a man made problem so why couldn't I get a new dryer? I think they treat customers the way they want and I feel this can't go on I am not happy with how things was handled
