[Resolved]  Flipkart — iphone 7 old stock sold

Address:	Chennai, Tamil Nadu, 600010
Website:	Flipkart.com

I ordered an iPhone 7 mobile by end of June 2018, and they sold me a mobile manufactured in Dec 2016. They Sold me old stock which is not acceptable. And the invoice states there is a return policy, I've not even opened the box as soon as I saw the manufacturing date on the box I'm very much distressed. But they are not accepting to take return or replacement. Please help invoice is legal.
