Asus India — Service disappointed. Want replacement

Address: 781018

From 10/7/2016 i am using asus zenfone2 max, in its first month only its main board and sub board got damaged dont know why even from the very first day i am having mic problem too but that was i ignored because i thought it may be because of network problem an all. But still the problm is same. Using asus is all perfect but satisfaction lebel is not upto the mark due to main board and sub board damage, and now mic problem. I am requesting you to take back my phone and provide me a new same phone and model.
O please kindly provide me a new one instead of this.
Thank you.
