Myntra.com — delivery related problem

Address:

Indore, Madhya Pradesh, 452010

Hello Myntra,
I am happy to see the offers provided by you. Actually i ordered a shirt and a t shirt through myntra mobile app. But my item hasn't been delivered yet.
And today i got call from your delivery boy, and just shocked with his behaviour while I'm talking about my address to deliver that item. No manners how to talk with customers and also threatening me by saying that take this item by yourself if you want it, i can't deliver it.
How can you do this if your are taking the delivery charges too.
