Amazon India — Amazon cancelled my confirmed order after successful payment.

Address:	Hyderabad, Andhra Pradesh, 500032
Website:	www.amazon.in

I have ordered a Moto G Turbo mobile and I have received the confirmation mail also from Amazon on 27.03.2016. But after some time in the same day I have received order canceled mail from amazon for refunding the money. How can Amazon cancel my order which is successfully placed and payment completed?
My order number is[protected].

I have the evidence for the order of the bill, snap shot of order confirmed page, payment successfully page.

I want my ordered item. I don't want the refund money as I have successfully completed my order in Amazon. It cannot be cancelled by amazon by its own without customer's permission.
