Pathetic TV quality from LG Electronics

I bought a 65inch LG SUHD tv. I bougth the product in Jue of 2017 which makes 2 and a half years old. The TV cost me R20000 which was by no means cheap. I do have an old LG tv that has lasted me long but clearly they make them now only to maximise profits and have you come back in two years to buy another. No wonder hisense has gained 35% market share in this market being taken from LG. Hi sense has a 4 year guarantee much better than LG and 30% cheaper. i escalated to customer services to a Shanice who laughs at my issue, senior managers at this South Korean company do not understand how to improve customer experience today. But hey many of these electronic companies have thought they stood on top of the world and then fallen down and shattered. MY MONEY WILL CERTAINLY ONLY BE ON HISENSE GOING FORWARDS
