Xiaomi India — After update camera and touch screen not working

Address:	Xiaomi india
Website:	www poco.in

I got an update on my poco x2 miui version 12.5.2 on 18/09/2021, after updating phone rear camera stoped working. From next day morning also the touch screen not working. I went to xiaomi service centre they refused to repair for free they told me repair cost 8500 to change the motherboard. Beacuse my phone is out of warranty.
on 3rd sep their company ceo mr anuj
came live on youtube and talk about same issue
( the video link is https://youtu.be/6JHUk3t_8yEl
and ask all user to fill a form for free repair but i talked to their custumer care and their service centre, they didnt even know about this and forcing me to pay. As this is a fault of company phone is damaged by their wrong software update.
So my concern is why i am not geeting free repair their is no liquid damage or not even any scratches on my phone then why i am not
elegible for free repair.
I reported a feedback complaint by their feedback app feedback id[protected] but not
getting any reply, i also want to ask why their
customer care not taking any action of my complaint
and i want free repair only if not provided then i
only have one option i will take legal action
