Dear @Daksha_R_Nair
Since the right earbud of your Nirvana Crystal Black isn’t working and the return mix-up caused your warranty claim (Ticket No. 54775816) to be rejected, you should immediately contact boAt support at +912269181920 or email them at info@imaginemarketingindia.com explaining the mix-up. Mention both products and attach proof of purchase. If unresolved, escalate the issue to the National Consumer Helpline (NCH).
If still need help, reply to us.
