Flipkart — Asus Rog Strix Laptop not replacing my laptop

Address:

Vaishnavi Summit, Ground Floor, 7th Main, 80 Feet Road, 3rd Block, Koramangala Industrial Layout, Bangalore, Karnataka, India - 560034

So i ordered this laptop on 2 oct 2021, and i received on 7th oct, so after 2 or 3 days o[censored]se i found some frame lag in display, then my Bluetooth drivers suddenly get removed I have to particularly restart it for Bluetooth and the last my graphic drivers crashed and uninstalled.so the very next day i contacted asus customer care for the issue so they told me that they are arranging an technician for my laptop and if the listed problem are there i will get an DOA and i can replace my laptop thhough my 7 days replacement gets over still i can replace
so the agent came and check my laptop he found that problem and applied for DOA but gets rejected from asus because of "out of DOA DATE"
because asus consider the invoice date has billed date so as per my flipkart bill invoice date was 3 oct 21 so from 3 7 days are 10th of oct and i got my laptop in hand on 7 th of oct so the period of returning passed out before i even seen the laptop
and now iahve complained to both the entities to resolve my problem of replacing but no one is responsing and the days are getting passed and passed then they will say now it cant happen i have every proof of problem that my laptop is facing though i am not getting replacement
imagine the pain i am having right now after buying your first laptop of around 1 lakh and still geting faulted piece and still not getting replacement too ...
please help me please
