Samsung South Africa what is going on with your TVs ??

Hi We had bought a Samsung 55” Curve TV in 2020 from Makro and approx 3 years later the TV stops working ps: not due to any load shedding issues but it keeps switching on and off and switching between channels by itself and sometimes not coming on at all as if it’s some sort of software issue. Back in 2020 to buy a 55” Curve Samsung Smart tv was an electronic purchase of a premium price and to have it last 3 years is absolutely pathetic quality. With absolutely no physical damage, tv is for my parents who are 50+ and literally watch the news on a regular . Unfortunately warranties only last 2 years and evidently nobody is going to try to assist us. From Samsung South Africa their quality has really deteriorated or is Makro selling off defected units personally I’ve seen lower end brands lasting much longer which has me thinking are we really paying for peace of mind and quality. The quality behind the parts put in and the systems used to operate these smart tvs are really at a questionable doubt. @Samsung I’ll really love to hear from you!
