takealot thinks I'm a fool

I returned an item for a refund (not credit) I have been tracking the item since January. On the 28th January it states that the refund has been concluded. I have completed approximately 7 online queries and NO ONE has responded. Today I managed to contact the call center (after a friend gave me the number) only to be told that the refund was credited to my next purchase. I downloaded said invoice and NOWHERE does it state that the amount was credited to this purchase. I paid the full purchase price + delivery. I am beyond dissatisfied with their response as it is not true. If they used the credit it would have reflected on the invoice PLUS tracking reflected REFUND concluded.
