Amazon announced Great Indian Festival sale From 17th -19th October.

So i searched deals and found a deal showing that the mobile price was RS.0.64 .
So i placed an order and paid with Debit card.
After that i got your order is confirmed, preparing to dispatch.
But at 2:16 pm i got mail from amazon that it is cancelled.

Message as follows
