You need to go to a reputed local repair shop, I know a few from Mumbai but Delhi will have to lookup. Something like this ideally shouldn’t cost you more than 5k in my experience.To get your data from the SSD, the part in middle of your battery and right fan, it looks like a network card but it’s just a small M.E 2230 size SSD. Take it out of there and put it in a NVMe SSD case or another laptop’s/Computer’s PCIe slot and you should be able to access the data.
This guy looks reliable from what I can see in the video but DYOR. His address and everything is in the description.
