Dell India — Overheating problem

I have dell inspiron 5593 and i am very much suffering with overheating problem, my laptop back side body overheats. And it starts overheating in 10 minutes from starting. Also my son cant play any game at all the games does not run smoothly it lags very much and also heats. Can anyone tell the procedure to replace the laptop with new one because i tried all the solutions which were provided by this community. And the phone service is very annoying. We have to wait 2-3 hours for a single call. I have purchased it on 6th july 2020 and the problem has started from the next day. Please find the solution.
