I had received a Mi Band 2 as a gift. It was purchased form Amazon.in on 14th October, 2016. According to Mi India website, warranty for the Band is for 1 Year. There was some problem with the Band and when I visited the authorised service center in Durgapur (Microsys, 2nd Floor, Kanak Bhawan, Nachan Road, Benachity, Durgapur - 713213, Opposite Indian Overseas Bank) they told me that my warranty was for only 6 months as I had purchased the device from Amazon and they refused to provide service for the defect. I repeatedly showed the service agent that on the Mi India website, Warranty is listed for 1 year, but he refused to understand.

When I came home and chatted with Mi customer service agent online, he reassured me that the warranty is for 1 year and requested me to visit another authorised service center.
Both the service centers are very far from my home and it is not possible to go to service centers everyday and when authorized service centers are denying service, why will they listen to me?
I want replacement/ refund of the damaged product as my warranty will expire soon and the service center did not take my product when it was within warranty. I have attached a copy of the invoice.
