Asus India — Rog phone 2

Phone keeps shutting down again and again while I'm playing games.
It is clearly stated from you guys(ASUS ROG TEAM) that this is a gaming phone, and we can play games for a long time( 5-6 hrs a day) at a minimum.
But after the update of ROG PHONE II, it has been the worst shutting down automatically and either than restarting it goes under loop of bootloader. Didn't expect this from you guys. It was the best phone TILL IT SHOWED IT'S COLORS. Kindly do something about it. Spending 40, 000 is a not a small amount from either a rich or a poor guy. It's a huge amount. Is there anything you can do about it at the earliest. If a yes reply back with an email on [protected]@gmail.com, will be very helpful and grateful.
