Boat — replacement through warranty

Address:

13/D1/A. Bheemanakolli road behind swimming pool, Mysore, Karnataka, 570009

I purchased my boat stone 1000 speaker through amazon on the date of july 16 and after few days it stopped working and then i claimed my warranty through boat complaint registration and they gave the ticket number which is 602733. The product has been picked up and already it has reached to the seller who is image marketing pvt ltd. I requested amazon to solve the issue several times and they delayed and the boat customer service is not responding to the calls and the mail has also been sent which again it has no response. I have attached the tracking id
And all the details necessary below. Please take serious actions.
