Terrible service warranty

I have bought a Hisense fridge on 14 January 2020 and it currently not working, 7 days now. I have notified both Makro and Hisense 3 days ago and my issue has not been resolved as yet.

A technician from Hisense came on Tuesday (2021-01-05) but was not able to fix the fridge. I called Makro again to notified them and was told by Thabisile that they will send their technician and the turnaround time is 2 to 3 days and she gave me a reference number ***. I called Hisense ***, Lucia picked up, *** and was told that the spares store is currently closed and the order for spares might take up to 10 business days.

I have asked Lucia what would happen to the food that is in the fridge, her response was "there is nothing that i can do from my side"

I have been told that the warranty is 4 years but when there is something wrong with the item, no one is willing to assist me.

I have sent emails requesting complaints departments contact details but have not received them.
