Quality of SUPER UHD 65uh770v is terrible

I bought one of your SUPER UHD 65UH770V units at Makro Woodmead last month (August 2017). After 2 weeks I returned the unit due to very bad uniformity on the panel. It had that whole "dirty screen effect". Terrible when watching sports and scenes that had one single colour as background, etc. I have photos to prove it.

Makro then managed to find me another unit at Makro Centurion. This unit had extreme back-light bleeding in 3 corners of the TV. The panel was flimsy, build quality really not up to scratch, especially when this unit is worth over R20 000.

I have always been a fan of LG's LED Television sets. But unfortunately after having to return 2 units (which is supposed to be one of the more expensive models), my faith in your brand has faded. As it stands now, I will never purchase another LG LED Television set and I will always tell my friends to avoid your 4K UHD Television sets. I really have never been this disappointed in your brand.
