Brand new fridge stops working less than two months after purchase

I bought a defy C600 (DAC700) fridge on the 7th of February. It stopped working on the 30th of March. This is supposedly one of their higher end fridges. First the fridge section stopped cooling, then the freezer followed a few days after. A call was logged via the retailer, up to today (5 April), noone has called me. I WANT THIS PRODUCT replaced because problems like this should NEVER happen so soon after buying it BRAND NEW. Defy is certainly no longer what it once was
