Fridge Issues at Game

I recently had an issue with a DEFY fridge I bought at Game. 4 Months later, the fridge stops working. I go to game and tell them about it since it was still under guarantee. They promise to send a technician to come look at it. The technician comes through and tells me it's the rubber, I should lower the temperature and give like a few hours it'll work again. Days later, the fridge is still not working - I head back to game. They promise to come fetch the fridge, I get a call from DEFY telling me they are coming. They come and they 'fix' something again and leaves. But still the fridge is not working. Now I'm furious and I go to GAME again and throw a fit - only they do they come and fetch the fridge and give me a new one. This is where it gets interesting - the fridge works for 5 days and it stops working again. I'm tired of going in and out that store with the same issue now.
