Makro Crowne Mines

I ordered a very expensive bottle of whiskey from Makro Online on the 25th of November 2023. Delivery is 2-5 working days. By the 30th I had still not received my package, so I cancelled the order and went instore to buy the very expensive bottle of whiskey. Despite the order being cancelled, and a reference number being given for the cancellation, the courier company still attempted to deliver my cancelled order on the 2nd of December. To date the store has still not cancelled the order, and therefore has not even started with the refund process. Please guys, I have contacted the call centre numerous times and they keep telling me the onus is on the store to sort out the refund etc. Can you get the ball rolling on this.
