Hindustan Times — oval solutions case- work from home.

I started working for this work from home captcha filling, within 2 days the website stopped responding and so i left doing it. Few days back a lawyer, anirudh krishnan called and told me to pay 9000/- within 2 hours nor they will issue a legal case against me. He is calling again and again, what should be done please tell.
Please help, is this company legal or fraud?
They sent me an agreement and are again again saying they have filed a case against me.
