Lenovo — Poor service from Lenovo, they made my lap more defective and now they aren't giving me replacement

Sent from Mail for Windows

So i bought my legion 5 15 ach6h with rtx 3060 (130w) ryzen 7 5800h, 2tb ssd 1080p bought for 1, 30, 000 inr in late February 2022, it was a beast lap until i updated to lastest bios 53www, which was broken and has caused issues for many legion users such as bsod on battery, drivers getting bugged and hence causing gpu to underperform but the problem doesn't end here, personally i had driver issues, laptop freezing and fps droping form 200fps to 20fps at first, i ended up using ddu to fix my driver issues but couldnt and lap started underperforming, i had good thermals like 90c max on cpu and 79c max on gpu but it raised the temps to 97c on CPU and 84c on gpu and even more ( not throotling) so i tried sitting in ac room and yes it lowered tbe thermals, but resultant was the same, low fps, like in gta 5 i would get 100fps but i started gettings 50 or 60 with huge frame drops (temps were fine as i sat in a room with temp 16c ), as a solution i tried multiple bios versions (reverted bios), clean installed windows from windows settings and even from bootable usb drive but nothing, i used ddu ( graphic drivers uninstaller) but nothing, i tried every driver version even those which lenovo provided, reset bios settings to default, . At last my lap started randomly restarting i tried flashing windows on my both drives, i contacted legion support they asked me to clean install windows again i mean what i already installed it like 30 times, but nothing they forced me i did, nothing new the problem remained, finally they agreed to send a technician after talking to them for 4+ hours first and 3+ hours next day on 7/7/2022, technician visited me on 8/7/2022, he came with a new motherboard, and started with opening my lap, he connected everything perfectly, but forgot to connect one of my usb port so he opened it again, he applied really poor thermal paste and he disabled tpm 2.0 and secure boot (two essential things for security) (edited)

[5:42 PM]

he disabled them to register my laps mtm, he had one thing that was to enable it again he forgot to do that, i m om with it if he forgot but now secure boot and tpm 2.0 doesnt turn on even if i try enabling it from bios as he guided, so it remains disabled, he stopped responding as he was in other replacement work he asked me to contact lenovo support, these guys again took remote access and checked everything like a hardware scan report, i tried showing him all the screenshot i had of secure boot error and yes i was throotling after 3 mins of opening any game my cpu used Ramp up to 105c and gpu to 87c both are throotling, also my many games are not launching which requires secure boot and even windows defender fails due to absence of secure boot., I called lenovo for more 4 hours all they did was told a technician will be visiting and taking a look at my laptop, wont change the heat sink or any part . I first asked for replacement they said replacement is only possible if i keep getting issues even after changing multiple parts, so i m ok i will wait and ask Lenovo to fix issues but as said i demand a refund or replacement as they promised me if that they will send a technician which yet hasn’t arrived, event after motherboard replacement my issue still persist and now I have multiple issue and the lap has become un usable, I kindly demand a replacement or a refund . I hope that you will surely help me .My lap randomly restart amd boots into a black screen and it flickers, my wifi card is not working well too
