Boat — BoAt Airdopes 131 stopped working and company rejected the warranty claim

Hi team,
I have bought boAt Airdopes 131 on 13 Jan 2023 and after 6 months one side of airbuds stopped working. I have raised warranty claim on 19 July 2023. Today on 25 july 2023 they rejected my warranty claim saying the product is damaged. I have sent my airdopes in a very well condition, even courier partner also inspected and then after inspection i have packed it in a small box as per the instructions.
Now they are saying the product is damaged, how can it be damaged when the courier partner also checked it.
Please execute proper investigation on this, i have sent the product in a well condition.
They have now damaged my product and rejected the claim so that i can not claim the warranty.

Please look into this. Please investigate it properly and check it with courier partner also.

Thanks
Anshu
