Game giving us the run around

We bought a Samsung fridge from Game in Heidelburg Mall, this was in July 2015. This was a demo fridge that was sold to us without a manual book at the price of R20000. The fridge started making a weird noise we went to report this to them at Game around September and we were told to wait they would get a Samsung Technician to call us. We have been waiting since. Now we again gone to Game on Monday the 9th of November to let them know that our problem was never attended to. They took our details and said we would be contacted within 48 hours. That hasn't happened. Now I don't know what their problem is because we bought a fridge that should work and it's giving us problems. Like we have to throw food out cuz the fridge isn't cold enough. They should take this serious as we are fed up with their customer service. We want this fixed ASAP.
