[Resolved] Apple India — iphone 6s decide motherboard dead with 1.2 years

I have purchased iphone 6s on may 2017, by the end of may 2018 the mother board got dead and the service center people said there is no use with that mobile, we cannot do service for that, even though i asked like i will pay money. I spent rs.40, 000/- for the mobile. Within 1 year the mobile is not working means what is the use of brand for apple. Please help me on this issue, why because that much money i didn't get easily.

Thanks,
Pavan
