Amazon India — refuse for refund

Address:

Aizawl, Mizoram

I order samsung neo 3 on 25.6.15 Order #[protected] and collect the package from courier office on 30.06.15 When I open it later, I found the mobile missing They didn't instruct the courier to deliver it to my doorstep. They sent me sms to collect it from courier office. So I went to collect from their office but I was in hurry as I have to go office so I didn't check and open in front of them. I have to give my signature to collect the package, but they refused to refund informing that I gave my signature.
