I have made a complaint regarding the imbalanced sound and mic problem in my boat basshead 100 and ticket no 2878413 and is generated on 21 July 2021 after that on 23 July I got the mail that my earphone will get picked up but didn't. On 29 July the Earphone is picked by the courier man having waybill number [protected].
After calling your customer care on 16 Aug and 09 Aug, give me a new ticket number 3056477.
I have mailed them multiple times but they didn't reply even once.
I have also called their customer care, they are saying to wait but didn't provide any solution.
