[Resolved]  Redmi — Pocox2 Faulty update

I've Redmi POCOX2 which I purchased on 1.3.2020 as my mobile works fine until my handset system update made available by company in November 2021 so customer can update their handset so I updated my device but after update my device unable switch on properly.
So I went to authorised service centre I explained them what happened as I've have written above then service centre associate said that your device is out of warranty so I've to pay for the repair which is 11000 rs approximate that was a big amount for me and they said that you can repair your device in local market, so I went there for repair but in market nobody could repaired my because the system update corrupted my device motherboard .
Then after few days I searched about POCOX2 system update solution there I found a large number of POCOX2 customer's device also corrupted by official system updated few of them were camera issue some had mobile unable to on issue. And few of customer's device is repaired free of cost after warranty expiration, So I also talked to customer support but they denied me. So now I want my device repaired because this is company's fault that they uploaded system update having virus which corrupted many devices, so in exchange company can take benefit customers hardly earned money. My mobile submitted at Redmi service center. Please help us
