Fridge repairs

I bought a refridgerator cash at Joshua Doore in September 2015 and within 2 days i realised that the water dispenser was leaking, i reported at and they said a tachnician will came and fix it but they did not. On 8 November 2015 the fridge was warm inside and everything melted, i just decided to take it back to the shop because it was clear that it was faulty and my understanding was it is under guarantee because i only bought it two months back. The Manager told me to take it back home with me because it is no longer theirs, and wait for the to send a technician. I siad i will leave it there because i cannot go home with a brand new fridge that is not accomplishing it's purpose, reminding him that they did the same thing and did not send the technician as promised the last time.
