Blue Dart Express — product not delivered on expected day of delivery

Address:

Venglai, A-35, Lunglei, Mizoram, 796701

I ordered three items from myntra. And at first the expected date of delivery was 23rd oct. But one of the product is said to be delivered on 25th oct. The others are on 23rd and i have not received any calls or have the items delivered.
I want to know what is going on with the items. And you should be responsible for such unprofessional act on your part. If it's delayed you should let the customers know. But here i am, checking my items and it is said it awaits delivery yesterday but i have not received anything. Do something about it and get back to me asap.
