BROKEN FRIDGE FOOD ROTTEN AGAIN

I bought a Hisense fridge at Makro Johannesburg Woodmead on the 11th of April 2015. 3 weeks ago I reported to the store that the fridge was not working they told me they would inform the manufacturer to get the fridge serviced they only arrived a week later and everything in the fridge had gone off. This didn't seem to bother the manager when I told him about it he said there is nothing they can do about that. The fridge is now not working again I reported this last week Friday (04/09/2015). Today is Wednesday no one has come to fix the fridge and my food has gone off AGAIN. I have been calling and calling but I am not really getting any help. Today I was told tomorrow they will come. This fridge is only 5 months old and is already giving me such problems. I am disappointed at how the store is handling this matter and disappointed with the brand Hisense.
