Boat — Warranty product taken away and not returned back

Address:	Mumbai
Website:	www.boat-lifestyle.com

I ordered my wireless Boat Airdopes 201 in February 2020 (from Amazon.in). Within 3 months o[censored]se, the battery life deteriorated to 10 minutes o[censored]se after full charging.
I requested for warranty replacement of the product. The product was picked up for replacement on July 8th. My complaint ticket no. is 1254280.
I have waited for almost two months now, but the replacement product has not reached back to me yet. Their customer care number is unreachable ([protected]) and they are not responding properly to my emails. They are unable to provide me the exact status of my product through emails.
I want to have my money back.
(I have provided the Amazon invoice, the email thread and the receipt provided by the pickup agent)
