LG Electronics — Faulty oled television LG65G1, picture upscaling not as advertised

Purchased LG65G1PTZ OLED TV on 10/11/21, picture upscaling not proper while watching sports, Sonyliv, Hot star etc, I have lodged various complaints to LG India, but technicians are stating that there are no issues. LG website states that picture will be crisp n clear due to latest processor but quality is not up to the mark. I requested for change in TV or return the TV n issue full refund. Further they are not giving in writing that the picture quality n upscaling has no issue. I am not at all satisfied by the product n wants full refund. Please look into the mater.

Further I am planing to sue LG India for deficiency in service n faulty product.
