Amazon India — order showing delivered but not received.

I ordered Redmi 5 32GB From Amazon India in first flash sale on Tuesday 20th March 2018. Item was shipped on 20th March from Amazon Transportation Services with Tracking ID[protected] and Estimate Delivery date was 26 March 2018. But Today in morning I received message on 10:14 A.M that your order is out for delivery by our Amazon delivery Agent mobile number ([protected]) and after 3 minutes i received another message at 10:17 A.M that your item has been b delivered.
Delivery boy didn't call me or and he didn't contact me.
So i didn't received my order but it has been delivered. Then i call on delivery boy([protected]). But he didn't received the call and after 10-15 minutes he switched off his mobile. And still he has switched off his mobile. Pls look at this and pls take action agenct delivery boy and Amazon Transportation Services.
