Ecom Express — shipping of product

The product was ordered from flipkart.
It is the fault of ecom express that the delivery man did not come to deliver and cancelled it on his own decision.
The delivery attempt was made on 3 days
He did not even call me on 2 days and 1 day he forgot to bring my parcel.
I could not call him because the delivery man uses company's mobile number so when we call them it connect in the company and we could not reach to the delivery man.
