Hi,
I bought boult audio neckband bluetooth headset on nov-18 via myndra,
My invoice number is [protected].

At the beginning its battery backup good.

Now it has a battery issue. Its stands for 20 min only.

I already mail boult on daily basis. But no response.

I call them too. But they not connect my call. Once i select the language its automatically disconnected.

Very worst customer service.
