Disappointed with Defy Fridge purchased from Makro

I bought a Defy fridge from Makro Alberton in April 2021 and from the onset I have been having problems with the fridge. I started realizing that my food would get rotten too quick and I thought maybe I got the temperature settings wrong and would adjust the settings and that would not help as the food would still get rotten. I then decided to log an incident with Makro and technicians were sent through and they told me that the fridge was fixed and that I will not have a problem again. Mind you, I believed them but then I realized that it would lose power again and regain it...Then all of a sudden again my food starts to get rotten again. I am a single mother struggling to make ends meet and whenever food gets rotten that's a huge waste for me. When I decided to buy that fridge, I chose Makro because I knew Makro sold quality products and I am so dissappointed with the quality of this product. At the moment I have a fridge full of food that is rotting and will not be able to wait long for technicians to come through. I would like this matter to be attended to urgently and also be compensated for the food rotting in my fridge.
