Ecom Express — rude behaviour of delivery agent

Delivery Boy doesn’t know how to talk with customers, He refused to come to the location & said that he will return my shipment. Behaviour is very rude even Seller won’t Behave the way this delivery boys behaved. Without delivering a parcel he went. I request Ecom Express to trained there staff well. I hope I will get a prompt respond to my matter
