Nokia — Nokia 5.3 Device got bend without any damage or crack

I bought a Nokia 5.3 device on Dated 30/Jan/2021, without any demage or break it gone bend from between. Voice issue is also there. And company is denying to give service. Phone kahi gira nhi, kahi se bhi tuta nhi, kahi bhi koi nisan tak nhi !! Phir bhi company wale ise warranty mei shi nhi kr rhe !! 5000 rupees mang rhe hai!! Aise bend q hua phone is tak ka answer nhi de rhe... Kal ko battery blast ho gya ya kuch bhi accident hua is device ki wajah se toh kon responsible hoga?? Meine photos attach ki hai.. please take action against this. I want replacement. Please tell me why I pay when there is not my fault !!
