Amazon India — Auto cancellation of order #[protected]

Website:

www.amazon.in

Hi,

I had placed the ORDER #[protected] of Moto G Turbo (White) on 27-Mar-16 with Amazon India. I used the promotional code which was offering this handset at price 4999. I received the confirmation mail today morning regarding delivery dates. But just now I got the mail that order has been cancelled & refund initiated.
As I had not cancelled the order, I called the Amazon Customer service, they said that it was technical fault & no promotional offer was going on that product.

It is Amazon's responsibility to check all the details before selling any product. It means, whatever sale prices they are offering are might not the discounted prices and they might cheating us every time!!!

I hope, I will get the product which was promised in discounted price & don't want the refund.

Regards,
Sagar
