Extremely disappointed with Samsung Television life span of 2years

I bought Samsung TV UHD 43" television on the 24 November 2018 and it was working fine till 15 Jan 2021. The problem is that the TV is displaying only in the middle of the screen and showing black on the side. I took to TV to Samsung service center called MM All electronics and was told to fix this would cost me R5700 ( Which is the current value of a new television with the same specs). So basically I was only able to enjoy this TV for only 2years 2months and now its completely dead. I am extremely disappoint with this samsung product which also makes me question the lifespan of Samsung television products .
