makro?????

I bought a fridge at makro last year and it broke, Makro sent out Defy to replace a broken part 2 times after the the fixed the problem it broke again. I phone Makro after they fixed it and told them it broke, they told me they will phone me to tell me if they will replace the the fridge since then they did not phone me it's now a month what I don't have have a fridge and I have 2 children I must keep the food cold I can't. I use a cooler bag to keep our food cold.
