Amazon India — the delivery boy behaves very rudely to my sister

The delivery boy behaves very harshly to my younger sister just because she did a bit minute of late in bringing the amount, how could the company allow such type of workers who don't know to play his role for which he's meant of his job. There work is only to wait for the customer to take the parcel, and just she was a couple of minute late to bring back the money he lashes.. This is not at all working.
