Delhivery — Courier boy was very rude

Delivery complaint
Behaviour of the delivery boy was really bad. He doesn't even know how to talk to customers. I asked him to come forward for my order and he denied, even argued with me. Kindly work on your staff. Either change the staff or provide them proper training regarding how to talk to customer. I would say i got the worst delivery service. Please do work on it.
