Poor customer service from Game stores Lichtenburg

Very disappointing to note that Game stores sell TVs with one year warranty then charge exorbitant price to have the warranty extended for another one to 2 years. I purchased a telefunken TV from Game stores in 2017 April. I opted to take only the warranty for one year. 16 months later in August the TV just died. Took it to them over 3 weeks with little progress. They would only talk to me and update me on the TV repairs should I call. Otherwise they dont even bother to call. Sometimes they promise to call back and they never do. I am so disappointed. If they can't help or provide this much of bad service then why should I as the customer consider them in the future especially when it comes to major electronics. Disappointed. I am yet to hear from them and I still dont have a TV 2weeks after authorising them to have the TV repaired
