Woolworths would not refund me to my credit card

I made a purchase for 3 garments online, but only received 2, yet Woolworths took the money for ALL 3 garments and have not refunded me, until I followed up with the call centre now… I paid R350 from a GIFT CARD (this was a birthday gift to me) and the balance of R58 was paid from my CREDIT CARD. Upon enquiring about the refund, I was informed by Thando Rotwana that they need the gift card number to refund the balance to my gift card. I threw the card away, as the entire amount on it, was used for this purchase! Now I am told that they need the card number, in order for me to get my refund!!! WTH! Refund me to my CREDIT CARD, as I partially paid from my CC too!! When I requested to speak to a manager or supervisor, conveniently, they were ALL in a meeting (the oldest excuse/trick in the book). Kindly refund my money to my CREDIT CARD, I can not be held accountable due to your systems not being up to date with what is in stock and what not!!!
