Xiaomi India — Redmi note 3 not booting up. No reply from customer care

I purchased Note 3 from http://www.mi.com/in/
My phone got damaged the second day. The site shows 10-day "Hassle-free replacement" policy. So tried to contact them from their helpline no.[protected]. Tried over 100 times, but it doesnt connect. Dropped them a mail, but they are not replying. Contacted them via their Chat service, the agent says only 1 thing: "Your request is in process". What to do with the phone now??
