Makro Online - NO delivery NO refund

I placed an order online on the 19th February 2025. Part of the order was delivered timeously. The remainder of the order was not delivered and i got a message to say that they had no stock and the order had been cancelled and I would receive a refund within 14 days. We are now at the 7th April 2025 and I have not received the refund. I have sent numerous emails, spoken to a lady in the call - center, yet nothing. My last correspondence was to say that I am taking to social media and also opening a theft case with SAPS. No one even bothered to reply. I fin this highly frustrating and completely unacceptable. How can a large business like Makro ***** their customer's money and not be accountable for it?
