India Post — post man denies delivery without bride

Address:

Mumbai City, Maharashtra

Sir,
Today I had a post delivery from RTO. So the post man denied coming home from delivery and told that he is returning the parcel to source. Then he came again and started telling me I should be grate full of him that he is delivering and he didnt even deliber at my house he asked me to come at my buildings enterance. Even after that he started asking for bribe. When I told him I am already paying delivery charges to post he said that from now he will be returning my posts and I have to pay charges.
Hats Off Indian Post what great service are you providing.

I need an apology from department and a serious action against the respective postman, even though the postman denied providing full name.

These are the postman's firstname and number:
