Amazon India — Order cancelled from amazon after prepaying for a discounted product

Address:	560055
Website:	www.amazon.in

I placed an order for moto g turbo (White) on[protected] at a discounted price of rs. 4, 999, after applying a coupon code i found on the internet: "gyjqj3yw"
I paid for the entire amount while placing the order and received an order confirmation from amazon india with order id: "[protected]". The e-mail also said that the product was currently out of stock, and that i'll get a confirmation e-mail and sms when the product is shipped.

On that same evening, i got a mail from amazon, approximately 5 hours after my order was confirmed, that there had been a technical issue on the website and they will not be able to send me my order.
If a coupon is being applied and confirmed on the website, then it is surely provided by the company. How can they not deliver my product and give me such a lame excuse for the same?
Top to that, they had my money for almost a week. This is such an unporfessional behaviour from the top e-commerce company in the world. First off, i don't get my product which i wanted and also have to keep my money with them for so long.

On my part, i want amazon india to send me the product "moto g turbo (White)", (Currently in stock) which i ordered for, at the same price of rs. 4, 999 and also provide me with a compensation of any amount greater than or equal to the worth of rs. 5, 000 for cheating me, the end consumer, and also causing harassment and wastage of my time.
Expecting a reply from amazon india in the least time possible.
