Damaged Fridge

I purchased a Defy Fridge from Makro Strubensvalley on the 02/04/2016. The fridge worked for fews days and then a exclaimation sign started to flash on front display of Fridge and all my Fridge items started to freeze. I called makro to report this and was told I need to log a call with Defy and they will log a call with their Customer service department. The salesperson name is Temba. A week later a defy tech came out and found the the PC board is blown. Now Makro wants to replace the board a new Fridge . This is unacceptable . When the fridge should be replaced under the warranty and guarantee. I need to be compensated for my stuff that was damaged in the fridge. The value of goods damaged R1000.
