Xiaomi India — Laptop refund issue

I have bought MI laptop worth of 56K on[protected] but we are facing some heating issue, later we have raised an complaints to check heating issue but without our concern they have closed request so we have directly visited MI service center and given our laptop to fix the heating issue. but no luck, they replied as its common heating across all the MI laptops, so i have left my laptop in the service center...so we have compared apple laptop with MI and service center people accepted that MI laptop is more heating.

its more than one month im not getting any proper responses from the MI customer care, now they said that we cannt refund the amount that is normal heating.
I want my amount back or else that heating issue should be resolved.
Please help me to fix this issue.
