Apple India — Airpods pro product claim vs warranty

Address: Aptronix India, MG Road, Bangalore 560001

Apple claims airpods pro as water and sweat resistant in their product description and comes with a 1 year manufacturing warranty. I bought this product on Oct 23 2022 on Amazon. While I have used it for regular calls, I have also been using it for last 2 months while running. My right airpods wasn't charging regularly (needs quite a bit of alignment for it to charge) and hence gave the airpods and case to Apple service centre. They havent been able to repair and after 20 days, have denied warranty coverage with their technical team claiming 'liquid damage'! How is this fair if the product is supposed to be water and sweat resistant? They have also not given me access to their recordings or transcripts of their calls when they informed me of this. What is the recourse here? Unfortunately i dont have a large twitter following to make my voice heard. And i dont use other social media.
