My laptop broke down in the second last month of warranty they took 4 - 5 months to replace parts and get me my laptop back but still, they did careless work which where

1. Didnt perform repasting even after changing the motherboard and even when they did they used basic ceramic thermal paste instead of liquid metal and in very bad manner.
2. They didn't inject the model name, serial number, etc. because they didn't know how, so I asked customer care and they helped me using Anydesk.
3. Last and very IMPORTANT during the repairs they damaged my wifi card and its connecting wires and when i told them to replace that they said the laptop is out of warranty now.

The thing is they weren't able to find fault with my laptop they kept replacing parts until it turned ON, like the display, motherboard, Keyboard, and god knows what, they also lost a few screws like of empty SSD slot and the screw of the ram cover
