Still no refund

I bought a swing for my new born baby on Sunday the 29th of November only to find that the sales lady gave a pink colour and I specifically asked for a green one because it's for my son. She assured me that the colour was correct only to find after driving 20km from the mall that it's not the right colour. The swing was also defective. I had to drive back to the mall yesterday for a refund . Im still waiting for the money to reflect. I phoned the store just now to find out why have I not been refunded only to be told that it takes 14 days. That is bull because my money went off as the card was swiped when I bought the faulty swing and I expect my money to reflect now as I have been refunded. The manager didn't seem to care when I spoke to her on the phone. I want my money ASAP.
