India Post — postman repeatedly asking for bribe

Address: Lucknow, Uttar Pradesh, 226003

Every time this postman comes to my address, and demands money for the parcels already paid. When we clearly denied he started harassing us by not delivering out couriers. Every time i have to call the company sending couriers to send them again. And many times i get the couriers with missing items. Today 7/28/2017 he came to deliver my brother's pan card, the packet was already open. He was giving lame excuses about that incidents. I seriously think that whatever he finds of his use he keeps it and if not he delivers it with the desire to extract money from us in form of bribe. I sincerely request you to look into the matter as we are students an often do online purchasing and i don't it to happen again.
