Faulty fridge

On the 27 December 2017 I bought a Defy fridge 425 L for cash at R5084 at Game Newcastle Mall. On the 10th of January 2018, the fridge started giving us a problem on the top drawer in that water is dripping on the inner walls of the fridge and the bottom drawer freezes excessively( unable to open or close because of the ice. I reported it and they came and fixed the rubber on the door by sticking it with glue but still it did not help. On the 26th of February 3018 I called Defy and reported the matter and told them that I need the fridge to be changed. They referred me back to Game and said they do not do exchanges. When I called Game they said I must bring the slip as a proof of purchase, They said they cant take the fridge back we were supposed to bring it back within 7 days (Which is shocking because I did call them and reported that the fridge is faulty), They said Defy needs to come to fix the fridge again at least 3 times. This leaves me in the dark because what happens after the 3rd time, to date I am still waiting for Defy to contact me. I am really not happy about the service I have received this far, how can a "brand new" fridge give me such a hassle - it's unacceptable
