Amazon — mobile phone was used

Website:

www.amazon.in

The mobile phone i ordered was a moto g4 plus on amazon and when it arrived i opened the box and the phone's original screen protection cover was replaced by a cheaper one which was scratched and was of cheaper quality. The earplugs and the charger was loosely packed. the phone box had a bill in it which was that the phone had been used before (before shipping address).
I am complaining the day i got the phone (28-jul 2017). I want a refund of it. This is not the first time i have returned a product to AMAZON. I wish it could be better if all he items weren't previously owned.
