Delhi Police — abusive phone call

Sir, i have recieved phone call from [protected]. The person was saying that he is calling from idea when i said it is not idea number then he insisted me to know which simcard i am using. All of a sudden when i refused him to give any details he started abusing. Please check this once this may be the part of some fraud.
This may be the part of fraud to issue duplicate simcard and then accessing bank details.
