Skullcandy — worst service - irresponsible. need solution asap

Hi team,
This is regarding my worst experience with skullcandy headphones (Venue - noise cancelling version). I bought this from flipkart during october - 2019 and used for couple of times. Seller here in flipkart is "supercomnet" also exists with other name "shreyash retail private limited"

Slowly i have noticed big issue in it. Battery backup is not up to the mark. Even if i charge headphones fully, battery getting drained in 24 hours (Without any use). Next i need to charge this again freshly. As per skullcandy the battery stay at least for 2 years if not used. This is a big problem and the reason of purchasing wireless headphones is not serving my purpose.

I charged my headphones fully, used it for just 2 min then i disconnected bluetooth connection and power off done to my headphones. After 24 hours when i tried using it, i am literally surprised that battery is dead completely.

I bought this product with a great trust and faith towards this brand but this is seriously disappointing experience.
I expect immediate solution to this

Either skullcandy cheated me or this particular seller "supercomnet" or "shreyash retail" provided fake or defective product.

Thanks,
Imran
