Delhi Police — Getting harassed from fraud calls

I have received a call person having mobile nummer registered in bihar[protected]. The said call asking details of atm and it's pin for renewal. He says he is from state head of rbi. Office and he is telling he will renew every bank debit card!!! After denying to give details he started abusing on call. The said person was talking in local delhi language but he has particularly bihari accent.

Please take action against these fraudulent calls.
