Boult Audio — No response from boult audio support

I purchased Boult over hear headphone 2 months before.

Suddenly, my headphone stop working.so I raise my complaint and they give me a ticket number 00211836.and told me to send that defective headphone, on the following address. ( on 6 Aug, 2021)

Its been a week and the support contact is not working, they're only picking up when I contact their business department. 12 August. 2021 still didn't got any response from boult audio company. They don't have any working support, and no warranty support at all. There's no way to approach this company.

Going to file legal complaint under Scam, if they don't mend their way.
