Optima sound bar battery backup

Me ne Audionic Optima Sound Bar online order kiya tha. Company ki taraf se product description aur marketing me 4 hours battery backup ka claim kiya gaya tha.
Lekin practically ye sound bar mushkil se 1 hour hi chalta hai, wo bhi normal volume par. High volume ya additional features use karne par battery aur zyada jaldi khatam ho jati hai.
Ye clearly misleading / false claim hai jo consumer ke sath na-insafi ke zumeray me aata hai. Main ne product ko fully charge karke multiple dafa test kiya hai, lekin performance advertised specs ke bilkul opposite hai.
Main chahta hoon ke:
Ya to battery issue ka proper solution / replacement diya jaye
ya
Full refund process kiya jaye .Product Name: Audionic Optima Sound Bar
Issue: Battery backup
