Defy Fridge freezer not working poor service

I purchased a 614l Defy double door fridge Freezer in July 2023 from Makro wit. Since then the appliance has randomly kept on to stop freezing and cooling for random amount of time and flashing an alarm code. This leads to my meat and groceries in my freezer defrosting and re-freezing. I have had to throw away about R8000 worth of groceries because of this. I have logged numerous callouts with Makro and Defy has replaced the motherboard 3 times. However the problem is still not fixed and Defy send me an sms saying they are coming out but never do and when I call them they say someone from Defy by the name of Bazil has cancelled the callout.
