Slow to replace faulty fridge

I purchased a Hisense fridge/freezer from Makro (Wonderboom) When it arrived, everything looked fine. After using it for a few days, I realised that the freezer was not freezing and everything inside was starting to thaw. I complained to the Makro store who then logged the complaint with Hisense A few days later, a technician was sent to my house to evaluate the fridge This is where the complaint starts - the technician was completely ***********, he checked a few things, flushed the water line with warm water, adjusted the temperature and said that it will take a few days, but it will be fine. So I waited It got worse I tried contacting the technician and he was no help, he kept postponing I went in to Makro and requested another technician The next technician who came immediately realised that the freezer wasn't working at all and said that he will write a report and that it will be replaced. My issue is that this whole process is taking too long - I have had to borrow freezer space from friends to prevent my frozen foods from thawing and spoiling. It has been 9 days since I first brought this to Makro's attention and it looks like this is going to drag on for a lot longer. I'm tired and frustrated
