OnePlus India — defective phone sold on false advertisement

Address:

122101

I bought a oneplus 7pro in june 2019. The phone had a hang problem and screen blacks out. Now there is a screen burn in the phone, for which the reason being given (By service centre) is due to high resolution gaming and videos. However when this phone was launched, it was launched as a pro gaming phone and high resolution video displayer. Which here is completely false as it is turning out to be. Thet are ready to replace my screen, however i play games and watch youtube as well, i am asking them to justify their false advertisement, because after warranty ends and if the screen burns again, they will ask money to replace the screen which is well over rs. 15, 000/-. I was sold a phone on false advertisement. I have already visited their service center and they have recorded logs of my phone, but cannot provide a satisfactory solution. Another advertisement/promotion of this phone by oneplus says, its "warp charging" and the phone should not heat while charging and watching videos which again is false as i have recorded the phone getting extremely hot during charging. Kindly help me sort this.
