Jewellery Exchange Question About Getting Refunds At A Jewellery Store? ?

Question about getting refunds at a jewellery store? ? - jewellery exchange

I recently went to a jewelry store on Boxing Day, since everything was half the price of 1 day, I had a gold chain that cost $ 300 900th in the bottom of the entrance, however, said no refunds, only exchange unworn within 30 days after purchase or the purchase price and, to a state.

But anyway, since I did not use the collars, but technically, I can not buy, I can not put $ 300 expected. Is it possible, they give me the receipt and asked me back $ 300 and take the collar of my position, because of the recent financial crisis?
