Dell India — INSPIRON 3505 wort battery performance and Adaptor stop working within 6 months

I have bought Dell Laptop .DELL Inspiron Ryzen 3 Dual Core 3250U (INSPIRON 3505)
online through Flit kart sold by seller Indospirit Private Limited. since the day I received the product the battery performance was very pathetic only 1.5 hour whereas company claimed min 3 hours battery performance. Suddenly after three months FAN start making noise and system automatically ask for booting. within a six months charger I got with laptop not working. How this is possible a new charger stop working within a six months this means the charger quality is very poor. I have another laptop of Asus and charger is working fine even after five years. I want please check and replace the product as I am doubtful about the quality.
