Pathetic Service

We bought a Hi-Sense double door fridge from Makro in Strubbens Vally on the 13th of January 2023. The fridge doesn't work properly from day 1. Technicians were sent out and they have concluded that the motherboard is an issue. It's weeks later and Makro is still giving us the run around. Today (10 February 2023) we tried to contact the person who was handling this (Justice), the number doesn't go to the store, goes to a call centre where the person that answered told me that they cannot assist with my issue. I asked for a manager but apparently, she was in a meeting. Makro has made an appointment to swop the refrigerator out today at 13h00. We have had no communication regarding delays or that they cannot make it. This was a very expensive refrigerator, and it seems that Makro and its management team doesn't care about customer service or satisfaction. I doubt I'm being unreasonable or difficult, they sold a reject refrigerator which was confirmed by their technician, but they are by all means avoiding handling the situation and replace my refrigerator.
