Boat — Warranty Replacement product not delivering. Not even providing any ETA

I raised complain (id[protected] with Boat for my earphone on 18 July.
my product was picked up in 2-3 days. and after 5 days (24 july) i received email that my warranty claim got accepted and they will ship the replacement within 5 days. but today is 1 Aug still not received any update on dispatch.

I sent multiple mails to them. No one responding.

I tried to calling the customer support number, but their employees are saying that they don't have any update on the product and hung up the calls.

Boat if you don't want to replace the product please send atleast my old product back. You are taking money and you are taking the product also. What is this?
