Boat — no response of my product boat rockerz 255

Ticket number :- 647592
I had filed complaint to the boat service center on 9th oct 2019 for repair and replacement of my bluetooth earphones (Boat rockerz 255) which are in warranty period.

Now while i am tracking my product with the above-mentioned ticket number it is showing that replacement received on 10th oct. But i dint got my product and any message, call or email about product dispatch and delivery.

I called to boat customer-care number [protected] several times but they not connecting my call to the person to talk on this issue.

I checked my order details by providing my ticket number and it saying than my product is already delivered.

But i dint got my product back till now it almost 3 months now.
