Ecom Express — Delivered letter to wrong place

Dear team ecom
Greetings!

I would like registered complain against my order with order number : [protected]. The courier boy who was suppose to deliver the order had not called me before delivering the order .
Just for sake of delivering the order he had dropped the packet at wrong place & marked as delivered. When i had checked with other wings people thereafter i was able to detect my packet. I called the customer care but they suggested that they will return charges . but i need that letter which is important to me.Request you to take some necessary action against irresponsible attitude.

With best regards
Rakesh kumar
