Xiaomi India — unable to avail warranty

I had purchased redmi note 3 from amazon.in on 27.10.2016. But on 26.10.2017, there is some display problem for which i have contacted the authorized service centre of xiaomi in silchar on 27.10.2017. But unfortunately they told me that my mobile can not be repaired under warranty. But as per the warranty manual that was given with the mobile, it was written that the limited warranty starts from the day the customer receives the item. When i told about this to customer care executive they asked me to mail amazon and to send one copy of the mail to them. For this i had contacted to amazon and request them to send me a mail about warranty. I have also contacted mi customer care but they told me that my mobile does not fall under warranty as it has completed 1 year. When i show amazon's mail to customer care of xiaomi in silchar, assam, they told that the mail was not properly written. Hence they need to contact mi customer care. Now what should i do. If it is written in warranty manual of mi that the limited warranty starts from the day the customer receives the item then why my mobile will not come under warranty.
