Amazon India — Proper Invoice not provided

Address: Thane, Maharashtra, 421302

I have bought R-033 TX HP 15.6 Laptop from Amazon on 06 May 2015. As per the policy I would suppose to get 1 year warranty, till 05 May 2016. But while registering the product I find that the warranty will end on December 2015. I raise the issue to amazon and escalate the same to the higher authority but no outcome occur. Moreover when I call to customer care they simply cut down my call. I have talk to supervisor Mr Imran of the Customer care, they just tell me wait for 2 days.Further I wants to add that product have some manufacturing warranty. Without proper invoice HP cant restore it. For the same I also request Amazon to send me the invoice. But the simply harras me. I want my money back with penalty.The invoice they provided not contain any serial no. From the last 3-4 months I have raise a query at least 15-20 times. Please help me for the sake of mankind.
