Harman India — sold defective speaker, denying to replace

Address:

New Delhi, Delhi, 110085

Let me start off by pathetic execution of jbl.
I searched for their service center near me then post visiting pitampura centre i got to know that service center no longer exist.

2. Then i called customer support and routed me to nehru place which was closed on working day without any notification - 26th nov.

3. Then i visited gurgaon service center and requested them to replace my defective go2 speaker which i hardly used thrice.

Then first made me wait for longer then said they can't help it since it's working fine as of now, it's again not working properly since i came back disappointing my mood.

You can imagine how much precious time and energy i have spent for this nuisance.

Please help me if possible.
