Game/ JVC - Terrible customer service and even worse products

I purchased a JVC 55inch Smart TV from Game. The TV started giving me issues before the warranty was over I took it in and only received the TV back after about 2 months. The same thing has happened with my TV not even 6 months later after repairs and due to the hard lock down where I couldn't take the TV back to Game, I'm now told it is out of warranty. I called the store almost every second day during stage 5 of locked down they were aware and this was before the warranty expired. I'm now being quoted R4000 to repair the TV when the TV cost about R7000. In total I would then be paying R11000 for a TV that isn't 2 years old. Are the new TVs only meant to last a year and a bit? I have been dealing with Game N1 city and this hasn't been a pleasant experience. I've explained to the store I would like a refund and to buy a new TV as JVC hasn't been good experience.
