Poor service from Game Canal walk, Game head office

I purchased a KIC refrigerator from Game Canal Walk in 2015. I also purchased an extended warranty which is valid till 2020. I recently noticed that the refrigerator was not cooling sufficiently. On 16th September I reported this to Game and mailed all the relevant documents as requested by them. A technician came to my house on 20 September and told me that the thermostat needed to be replaced. Despite numerous calls to Game Canal Walk and Game Head office in Durban the refrigerator is still not been repaired. The reason given is that no spares are available. The spares are apparently arriving this week. I have been without a refrigerator for 3 weeks tomorrow (Monday 7 October). The service I have received is dismal to say the least. I have a list of names of Game employees who I have communicated with. One lady at head office in Durban was very rude and abrupt. No customer service at all. I will never purchase another appliance from Game.
