AirPods Pro 2 Hardware Failure (SNR/HDI) with zero damage: Denied free service despite proven internal fault. Advice needed!

i purchase airpods pro 2 in october 2024

within 18 months

i experienced an issue with the left airpod

it stopped charging and after some days it totally stopped working

when i checked apple support for this issue it mentioned to forget my device

when i did the airpods stopped appearing in any of my apple device

even after multiple times restarting my iphone and resseting the airpods, still the airpods wont appear to connect

i visited apple authorised service center and there my airpods pro 2 were diagnosed with SNR/HDI kind of internal issue

the expert said the airpods are not repairable and has to be replaced and it will cost 9400 INR

to which i asked him my airpods never had any occurance of falling or mishandling then why this issue came

he mentioned it can happen anytime

so my question is that why shall i pay such a hefty amount that is almost 50% of MRP of the whole product for a fault in which i had no responsibility

kindly tell me what should i do now
