MAKRO USELESS & SHOCKING SERVICE

I order my necessities from Makro online as the closest supermarket to me is 40km 1 way. Every single time there is something in my order cancelled & refunded due to no stock availiable, this is understandabile. This last order 21/10/2025, I ordered & paid for ×2 boxes (6 Packs) of long life milk & it was not delivered with the rest of my order. I have 6 or more ref numbers & still no milk which I desperately need. All Im told is to return the milk for a refund & reorder it. What must I return if I did not get it??? Why should I have to pay delivery costs due to their neglegence?? Surely the person / store that made this error should be liable for costs. All they have to say in the emails is that they are esculating it to the store. I managed to get hold of a person to speak to, not a bot, & he will investigate this issue. THATS IT!!!! I sure hope someone will resolve this now & deliver my goods PAID for already, its going on now for 2 weeks of this ****.
