Apple India — iphone 8 logic board gone in 1 year 3 months

Address: 560037

I had purchased iphone 8 on 14.03.2018. Just after one year and one month the set got shut down and its not restarting. I had sent to authorised service centre it is saying hardware problem and it is irrepairable.
It costed me rs 64000. And in just one year it is dead.
Its just pathetic.
Atleast the phone should be repaired.
This has happened with me twice on two iphones one iphone 6 and iphone-8.
We have spend our hard earned money to buy such costly set and it is not being repaired.
Its just pathetic.
The phone is in very new condition and even does not have any scratches on it.
It has been handled also properly. How come hardware issue come
