Boat — Issue about warranty claim

I raised a complaint in boat on 16th february for ticket id 979049 & 1055781 as one/both sides of earphones were not working.
Its nearly june end. The product was picked up from my house from xpressbees long months back. Yet there is no confirmation about the product delivery. The product was picked n is now currently under the status of whhandover. I have waited long enough for the replacement/repair of my earphones. I tried calling the call center of boat and xpressbees, but both are not picking up. I want my earphones... Kindly help me with this issue
