Elite Services — Harrashing for money by blackmailing by sending mail, calls and messages

I received a whatsApp msg from arpit sharma for job. He asked me aadhar card as address proof. I send it. After that I came to know that company was fraud. So I cancelled my work by sending mail to the helpline provided. Then they send me a notice from a lawyer to pay 11600 and then called me and messaging me to pay and sending notice. Pls take action on it.
