Typejob.in - Fraud job

I received a call from Typejobs.in and they lured me with their attractive offer of money. I sent them my Aadhar Card, but, not signed their document. I was told to write me name instead of signature. I wrote my full name and sent the mail back to them. The very next day, I thought of checking their legitimacy, and found the same is fraud. And, they do sent me a mail of work, but, I did not perform any task and their login was intact and untouched.
Now, after almost ** days, I received a call from their Legal Advisor, but again I didn't responded back, to which, he sent me a message stating that I signed the document,and,my response to them, again was negative. I told this advisor, that I didn't signed any document. His name is Adv. Varun Rathore.
Please suggest, what could I do, if they send me any legal proceedings?
