Nv Technology — blackmailing and fraud

Address: Aurangabad, Maharashtra

I received a call from nv technology on 16th of oct2019 and asked me to do a job that is click 150 links for 10 days and you will get 5 rs per link. I agreed and after registration i came to know that it is fake. So i stopped working and now after 10 days an advocate sent me a notice in my mail. The advocate's name is harish reddy
Aurangabad, maharashtra (Mh)
They are calling from this number [protected] and asking me to deposit 3000/ - in company's bank account.
Its look like they black mailing me and threatening to making the payment.
So please if you could help me to teach them a lesson. It would be very helpful.
