65" Smart UHO TV

I bought a TV a 65" Smart UHO TV at Makro on 9 May 2024 for R7999, last week the TV just switched off, no sound, no picture, I called LG they advised sending out a technician to check the TV it would cost R4000, I opted for taking it in today. They assessed it and said the panel board needs to be fixed, and it will cost from R7000 to R11 000. Does this even make sense to fix a TV with more than what I initially paid for and also, it is literally 2 years old, whose fault is it that LG is making low-quality products? I am so furious, this is insane. Why are you producing things of low quality and charging customers an arm and a leg to fix your mistakes???????
