Ekart Logistics — Delivery boy misbehaved

Delivery boy misbehaved. What one will accept what not that's mone of their business.. why should I answer him that why I am unable to receive the parcel ? How dare they ask me reason for not receiving or why have I ordered ? Who are they to ask ?? And how dare he asked me not to order again if Could not received the delivery .. they should educate their delivery agents how to behave and how to do their job.
