[Resolved]  Easy Solution — threatening for money

I received a call from [protected] regarding a home based captcha solving job they said they dont have any registration charges for joining. They have taken my aadhaar card for agreement and they sent me a link as agreement but when i tried to open its said you are successful registered. I haven't seen any agreement and they haven't provided any job. Now after few days i received a mail from advocate. [protected]@gmail.com, anil gupta as advocate threatened me to fill a case against me or i have to pay. I refused to pay. After few minutes i received 2 message from bw-arbitr ""mr/ms. Amit kumar sonar, this is to inform you that your internal case 2235299 has been listed on[protected] for legal proceedings. Kindly call on [protected] for further details." and "under sections 420 of the indian penal code you need to clear the dues of the company and settle your dues, otherwise court behold the right to take strict action against you. Call on [protected] for further assistance." they called again from another number [protected] and asking have you received the message in threatening voice. I clearly told them i will not pay a single penny an disconnected.
What should i do if i received a call again and also they have my aadhaar copy. Please suggest.
Thanks.
