Redmi note 6 pro - Overheating Problems in Device (rRedmi note 6 pro)

I bought Redmi note * pro mobile by flipkart ecommerce on january **, **** which sent to me on ** january **** it was heating and bettary is draining in one day cause of this problem I requested flipkart to replace it but they refused to replace it then I am using it now this problem have increased and it is getting heat in using mobile data, while charging, while using hotspot and show message on screen that "your device is overheating. Mobile data,Wifi Hotspots, Gps, and camera will be restricted". I visited twice within three days to Mi service center chhindwara to solve this problem but Mi person checked out it I showed him the message of overheating and said to me that there is no problems in device and I can not do anything for this problem and said that if you show me the problem in service center then I talked to Mi, But this problem occures at my home and other places but not in mi center and I can not go to Mi center to use my device there properly while I use it every place where I go and temperature of chhindwara Mi service center is cool that is why this problem does not appear there and they say show me problem here. I want to replace device or motherboard it is in warranty period.
