Non delivery of online purchase

Ordered fridge/microwave/snack witch on 27 January. Delivery commitment 2 - 5 days. Now day 11, no delivery. Makro says processed and would be definitely delivered yesterday and again today. Zip! Courier company have order number but goods not picked up yet, even though Makro say they have. My son at university is missing lectures waiting for promised deliver days. Inconvenience in not being able to cook or preserve food. Absolutely clueless, useless service.
