Bose India — Bose 300 soundbar just 3 months not work in bhubaneswar. 3 week bad response .

We purchased Bose 300 soundbar from Ample Retail online store (hyd) on Nov 2023, its just 4 months. Its not working, remote battery was changed and tested not working. Bose sound bar too nothing is coming no sound.
It turns green and turns red.
We registered to complain at bose India, they gave us Kolkatta's number.
We are in BHUBANESWAR, Odisha, and there is no service center.
Bose what up number least responsive they say talk customer care and customer care says talk technical.
They gave Kolkata number and that guy said u have to bring the same here.
its sick no service in Bhubaneswar and they are playing around for 15-20 days of now.
