No refund after two weeks of waiting

We bought a Twisp from the Brooklyn Mall kiosk on 3 January, the lady sold us the wrong model for my husband, it was too strong, so we returned it the next day and I was told there would be a R400 service fee because they cannot resell it, I agreed to that (reluctantly) and left my banking details with Alicia for a refund of R720. <br> It is now 19 January and still no refund and best of all she told me last week Wednesday that the payment WAS DONE and would reflect yesterday. This was my first experience with your company and hopefully the last - I do not appreciate being taken for a fool and having my money kept from me. You had no problem charging my card for the money, and now I have to wait. I feel sorry for future customers if this is your idea of service.
