Makro accepts online orders and doesn’t deliver

Placed an order 6 days ago to the value of R1103. All items ordered were in stock according to the online website. The delivery commitment was 2 - 5 days. They sent one courier with 4 cans of peas after 4 days and another courier with 1 can of food on the same day. Value R53. No communication from Makro. Have called them twice. Have been told that they sold the goods after accepting my order and that it has been escalated. Have emailed and had no response. Essentially Makro is selling the same goods multiple times. Call center’s response is “I don’t know when they will delivery. I’m not at the store. It’s because of the Coronavirus”. Makro should not accept online orders if they are not able to deliver.
