DEFECTIVE PRODUCT DEFY SIDE BY SIDE FRIDGE

I bought a defy side by side fridge , its not even 7 months and DEFY want to take in for repairs , the cooler stopped working and the freezer become the cooler on it own. I had to bear such a lost and defy and makro is working at there leisure to sort this matter out. not like most people have a spare fridge laying around as for feed back no one gives any from both defy and makro , I have to be the one keep calling to find out status. people please respond and tell me who should be responsible for the food that I had to throw away due to a defect on product. if this fridge can give problems less than 7 months ,what will happen next 7 months if problems again repairs again .not happy level of service from both sides
