I want my money back

Good day,<br> <br> My Fiance purchased a set of a chain and earrings for me as a gift for Valentines. However, he was not aware that silver irritates my skin. I returned the goods to the Centurion mall store on the 16/02/2016 with the intentions of getting a watch but unfortunately they did not have what I liked. I then requested a refund, so they refunded the card that was used to purchase the goods. I was then informed that it could take up to 48 hours to get the funds in the account. It is now over 48 hours and still nothing. I then contacted the branch and was informed that it could take up to 14 days to get the funds, now this is totally unacceptable for me as I purchased the goods and paid American swiss immediately, they have their goods and here I have nothing and must wait. I contacted my bank and they informed me that it was up to American swiss to sort this out with their bank. I need that money please.
