Amazon India — Moto g turbo order not fulfilled after confirmation by email 27/3/2016

Address:	Mumbai City, Maharashtra, 400056
Website:	www.amazon.com

I had ordered moto g turbo on 27th march 2016 from amazon.in.
With the use of promotional code amazon gave the mobile on discounted price.
i got an email of my order placed.
and today they sent me another email that stated

"We are writing to you about your Amazon.in order #XXXXXXXXXXXXX.

its not the fault of a consumer. as they had it on their site and when added the promo code it accepted it.
when its time to full fill their order they are running away from it.
