India Post — Rude Behaviour of The Postman

Address:

India Post Office,Tehsil, Bulandshahar Road, Hapur 245101

Today i received my package through Indiapost, it was my first time experience and the postman named "Charan Singh" called me and started the conversation in a rude way like an egoistic person does to their worker. However I still talked to him in a nice way and told him where to come yet he was being mean and rude and told me where to come instead of coming to my home i had to walk up to him for 200m while he was talking to me in a rude behaviour i hated this as much as I could but couldn't argue with him due to him being a senior citizen i hereby request the manager to reach upto him and punish him for the behaviour.
Thanks
