Harman India — 7 months still didn't received product

Address:

HARMAN India International Pvt. Ltd., Prestige Technology Park 4th floor – Jupiter (2A) Block, Marathahalli Ring Road, Bangalore – 560103, Karnataka, India.

I have bought a jbl bluetooth speaker (Product of harman) on october 2019 and i had charging issues with the product and i returned the product to the jbl customer service centre on february 2020. Still now i haven't received the product. I have called them more than 20 times and emailed more than 10times still i didn't get any proper response. They are always giving a false promise like my product will be shipped within particular time from the initial days and still nothing happened. I got mental anxiety with this people and this is the worst customer service i have ever faced in my life.
