Asus India — asus mobile zenfone 3 max model is overheating problem

It has been two months buying zenfone 3max mobile and it's overheating. I have complained twice in service centre jamshedpur jharkhand. But this mobile still have problem of overheating. They often say we have updated the software of mobile and now it's ok. This act will force me to go consumer forum if my grievance is not resolved. I think shopkeeper cheated on me
