Amazon India — items not delivered and payment already made no response from amazon

Address:

C/o State Bank of India, Bundgarden branch, Grace building, Dhole Patil road, Pune, 411001

On 22nd september i made an order of 6 books (Please see my orders from my account) for which i received a message that 5 books will be delivered on 24th september and another one book will be delivered on 28th september. I have received a package on 24th september and the delivery boy sent me a message for online payment. I have made a payment of rs.2407/- which is for five books. The package i have received had only two books. I have called the customer care people and explained the issue, they made me to talk with some special team, they told me that it will be resolved in 5 days but later on there is no communication at all from amazon. I just need my money back or else deliver those books immediately.
