stuttarfords goods return policy

i bought a dress on friday the 18th december at stuttarfords in rosebank mall for R1200. when i get home i tried the dress again and it was too transparent. i returned the dress today on sunday the 20th december. i was told that i can be refunded by a voucher. i do not want a voucher i want my money back. it looks <br> like stuttarfords is forcing me to buy from their shop. i am going to a wedding on saturday the 26th december i need something to wear. i could not find something i like on their shop and most of their dresses are very expensive. i cannot be forced to buy from them, they told me that their voucher will be valid for 36 months. i need a my money to go buy somewhere. i also think that it is the sales lady/cashier duty to explain to customers about their goods return policies. I REALLY NEED MY MONEY BACK NOT A GIFT VOUCHER THAT I AM NOT GOING TO USE
