Truecomretail — Recieved defective phone from flipkart through truecomretail please refund it or replace it

I recieved a defective phone from flipcart.
I bought the phone for the sole purpose of good battery backup but the phone I got has a battery issue. It's battery is draining very fast without even using it and the screen is also unresponsive most of the time. I raised return request three times and the request the request got cancelled every time .the technician that came to check the phone told me that this happens with all the phone . It's a brand new phone these things should not happen in a new phone.
Please accept return and give me refund asap for the faulty product delivered
