Abuse over mobile phone blank calls

I am getting blank calls for the past 1 month and sometimes the user use abusive language as well. I would like to register a complaint against that mobile user. I did FIR for the same. Can you please let me know the procedure of the written complaint for the same in consumer office?

Details of those mobile numbers are:

Thanks,
