[Resolved]  Reserve Bank Of India [RBI] — fraud letters in name of rbi

Hi, i m lodging this complaint on behalf of my father who is caught by some of the fraudsters claiming to be insurance agents. They send them regular fraud mails saying that your money will be returned and ask money in return. Everyday they call him and ask him to talk to many women involved in this scandal and misguide him.
Please help. He dont believe that his money will not be returned and says that this letter is a authorised letter from rbi.
Date since started - 2012.
Mails receiving from various people - ivdservices.[protected]@gmail.com, igms. [protected]@gmail.com, sebi. [protected]@mail.com, [protected]@gmail.com.
Some of the fraud mails attached. (Rbi letter, fraud cheque)
Help us to get out of this scandal and the amount taken from us in name of this.
