OnePlus India — OnePlus 125.7 cm (50 inches) U Series 4K LED Smart Android TV

I have purchased a OnePlus TV through Amazon in the month of December, 2021. The TV started malfunctioning (horizontal lines on the screen) since more than two months. I have contacted the customer care vide Complaint No. INSI[protected] and a technician has inspected the TV in the month of August'22 and stated that the panel is to be replaced. Nothing has been done after that despite speaking personally to the customer care several times. Every time when I contact customer care, they tell the issue will be resolved in 24/48 hours. But in my case several months have been elapsed, but the issue remained unsolved. I experienced the same problem at the time of purchase for installation of the TV.
