Faulty Fridge

Hi, I purchased a two-door fridge from Game, Kenilworth Centre, Cape Town in June 2020. 3 weeks later the fridge stopped freezing. We immediately contacted Game and was told that someone would call back and a technician would be sent out. 2 weeks later, no call and no technician. We then called back and were told again that we would get a callback. In terms of CPA, we are entitled to a replacement as the fridge was reported faulty within 30 days of the delivery. Why are you not getting back to us? A fridge is a necessity and we spent a lot of money which you were happy to take but the after-sales from Game has been absolutely horrific. I am appalled at the lack of communication and customer service. Get my issue sorted ASAP or I am taking this further.
