OnePlus India — Ignoring Free Service for Green Line Issue after Software Update in OnePlus Nord

⚠️ OnePlus SCAM⚠️
I have OnePlus Nord which was showing green line issue on the display after software update and OnePlus said they are doing free service if there is no physical damage or water should not affect hardware. It's fine.
I bought the phone around august-2020 which they saying warrenty expired and asking me to pay Rs.13k for display change.
There is no physical damage inside and out but they are intentionally refusing to do free service.
It's a software update issue made the green line issue. They saying the green line issue happened only for OnePlus 8 and 9 series models.
But this OnePlus Nord released on same year where OnePlus 8 series released.
They are refusing for do this free service which make user to pay heavy amount and building their empire.
It's chinese smartphone please make a note.
I was not aware of this green line issue for OnePlus phone before. If I knew this before, wouldn't update itself.
