Ravet post office

I had an registered post for rc book from rto. It had been more than 5 months that i didn't receive the rc book.
When enquired at rto, they said it was already dispatched 4 months back.
Then later when i enquired about that in dehu post office, they said it's was already delivered by them.
Then i got the name and number of postman who delivered it. He was the person who does fraud, keeps the parcel with him and asks for money in return.
Post department should keep a vigilance on these people who do fraud and loot peoples time and money.
