Amazon India — Not giving the gift vouchers of INR 8000

Address:	Bangalore, Karnataka, 302001
Website:	www.Amazon.in

I bought an iPhone 7 from Amazon.in on October 01, 2016 when Amazon had an offer that the customer will get Amazon Gift Card worth INR 8000 along with HDFC Bank credit card cashback of INR 11000. They clearly mentioned the HDFC cashback will happen by January 05, 2017 however there was no information about Amazon gift card of INR 8000.
When I tried to get in touch with Amazon, I was told that I will get my gift vouchers of INR 8000 by Nov 30. Even on Nov 30 I did not receive anything. Upon contacting Amazon, I was not offered any help and they again sent me a mail stating that I will get the Gift card by Nov 30.
Late in the evening I finally got an e-mail that I will now get my vouchers by December 31, 2016.
Its been 2 months already since I bought the phone and they haven't given the gift card. Now they are again saying that it will take another month. Amazon did this false commitment to increase their sales of iPhone. They don't have any intentions of giving the vouchers to customers.
I have 2 e-mails from Amazon committing that I will get the vouchers by Nov 30 (screenshot attached) and still they are not giving.
Somebody please contact me so that I can file a legal suit against Amazon for not giving the vouchers for 2 months and now again asking for 1 more month.
Amazon has done this fraud and I am sure they must be doing this with all the customers who bought iPhone 7 during that offer. Amazon saved all this gift card money by showing the fraud gift card messages to customers.
