Avi Enterprises — Fraud and mental harassment

I was looking for online job and applied on quiker and got a call from avi enterprises. They offered me a job of captcha typing but i didn’t accept anything from my end but after a month they started calling me and threatening me about legal notice and today again i received a call from a person saying himself lawyer at hc. I am not understanding this thing despite so many complaints against this company, why it is still harassing innocent people. Govt. Should ban this company.
