Ecom Express — No contact of service

Address:

Iritty

I made a 2 order from different website but their courier service is Ecom express. I made the order 3 weeks before and received message that parcel out for delivery but never got a call or saw a attempted delivery. Now the status of order shows shipment RTO lock. Please make the delivery soon as possible.
