1999 — abusive calls

Address:

Kolkata, West Bengal, 700096

The number I am receiving abusive calls from is[protected] and Truecaller app shows that the caller is Aditya Rai from Bhumihar, Bihar.
He has a email address [protected]@gmail.com

He called me on 3rd of November afternoon for the first time and as I picked up, he started to use extremely abusive words and slangs in Hindi. Moreover what was most scary was that he seemed to know a lot about me. He even said where I lived and what school I went to. I'm positive he isn't someone I know. He called repeatedly that day and I blocked his number the same day. I've recorder one of his abusive calls as proof.

I would be extremely grateful if you kindle take necessary steps against this miscreant.
