Samsung and Game have disappointed me

We bought a Samsung fridge in 2013 from Game at Lake Side Mall (Benoni), the vegetable rack fills with water and we have gone back to Game to complain during the past 3 years and every time they send someone to repair and this has happened 3 times already!! Now the problem has started again and when we contacted Game once again said they will send someone to repair it and I am saying no, because they have repaired it 3 times so I don't see what is going to be different the 4th time.I then said to Game that we want a new fridge or our money back because we don't expect such from a Samsung product.Game said I must call Samsung which I did, Samsung then tells us that our warranty with them ended last year and that we are now on an extended warranty with Game which ends next year March 2017. So Samsung says this is no longer their problem and that we should speak to Game, but now Game is refusing to give us a new fridge they want to do repairs of which we do not want this. This fridge has been problematic ever since the duration of the Samsung warranty. The fridge we had before this one lasted over 15 years so why is this Samsung fridge problematic when its not even 4 years old?
