I purchased this wireless earphone in July 2019, and now facing issue with its battery. I registered complaint and they said they will verify and then send the confirmation mail. It's been more than 2 weeks now but did not receive any mail. So tried registering the complaint again but again same thing happen and do not receive any confirmation mail or message. I tried send them email also regarding this and in response they sent the same link and asked to register the complaint. I called customer care also but customer care executive is not picking the call.
