Amazon India — PS4 Game - Not delivered but status set as Delivered

Address:	Bangalore, Karnataka, 560067
Website:	www.amazon.in

I ordered a product Need For Speed: Rivals (PS4) with order # #[protected] and tracking ID[protected] on 28/12/2016 with same day delivery option.
I did not receive the product on the same day. i escalated it and the agents asked me to wait for a day. Next day I got a message saying my order is delivered with customer signature as "GK. My name is Mohamed Ziavudeen.
I did not receive the product and did not get any call regarding delivery.

Why I should wait for 5 days to get the product back. Amazon promised me for 1 day delivery and should i wait for 5 days.
Why Amazon cant give my money back.

Amazon's agents did not even understand my situation and keeps disconnecting the cal..

Being an educated person, I am unable to handle this situation and I am unable to get a proper reply from Amazon.

Government is promoting cashless economy and these online Shopping guys are using it to loot money from people.

How will an uneducated person handle this situation?

Please take necessary action against Amazon and help me to get my money back.
