Boat — Warranty claim for the Replacement of boat BassHead 109 black earphones

I purchased boat BassHead 100 black earphones from Flipkart on 3/12/2021.They stopped working suddenly.I registered complaint on boat official website, emailed on boat support lifestyle for replacement of my earphones as they are under warranty period many times but didn't get any response .I am facing problem from a long time.Please help me to get my earphones replaced and provide door to door replacement service as there is no service centre nearby.Please reply and resolve m issue as soon as possible.

Thanks & Regards
