Nokia India — worst model of nokia

I want to complain to the company regarding their worst model nokia6. It has been only 10 months since i have brought the new phone from online as it was the new launch so it was only available online. It hangs numerous times in a day. It has a worst battery backup as one can ever thought.. The full charged battery just lasts for about 7 hours. Not only this it takes more then 3 hours to fully charge the battery. The third problem in ths set is there is a line flickering on the display. And the most annoying problem is the temperature of the handset rises to 47℃ celsius. It gets heated to unbearable temperature. Which is very dangerous as it spreads highly toxic rays. Which harms the individual. So i want the company to just exchange the handset. Otherwise i will be going to the consumer court.
