NO REFUND ON GOODS NOT PROVIDED

I bought articles online in December 2024. Some items were not available and they credited me and the rest of the items would be delivered next day. After MANY runarounds re courier and delivery I opted to collect from Makro Cape Gate. Being just before Xmas I spent a great amount of time waiting to collect the parcel just to eventually be told that they did cancel the order. I immediately went to refund counter that presented me with refund slip and said it would take 2 - 10 working days to reflect. That was 12 December 2024. We are now on 6 March 2025 and still no refund. I have gone to the store on numerous occasions with proof that I did not receive the funds but keep getting runaround regarding this refund. Would really like to know if this is common practice of Makro not to refund you for goods not received? I have also tried to speak to manager directly but get stonewalled and keep getting different staff member that even provided me with proof of refund - only problem is I still do not have any refund three months later.
