Amazon - Wrong item delivered

Dear Sir,
I placed an order for Macbook Pro **** MYDC*HN/A worth Rs. *,**,***/- on Amazon on **.*.**** via order number ***-*******-*******. After availing a discount of ****/-, I paid *,**,***/- for the same. The package was delivered to me on **.*.****. When I opened the package on the **th March ****, there was no laptop inside. The box was instead filled with a pack of printer sheets. The box with the laptop and its accessories was missing from the package.
I am a regular customer of Amazon and I have bought many laptops and other products earlier also from Amazon and like always, I placed my trust in Amazon when placing a prepaid order for such a huge amount. I have not only been cheated but, the trust that I placed on Amazon has been miserably breached. When I contacted Amazon, I was told that a resolution will be provided by **th March **** but despite my repeated efforts I have only received information that they are looking into the matter. On **st March **** they sent an email stating that the item was delivered in intact condition and they wont refund.

Request you to take a strict action towards the culprits and help me get my hard earned money, which is blocked with Amazon at present at the earliest.
