Onway Solution — online job fraud

This company employee's has called me for online job first and i agreed to do the same first. After that, i was unable to access the work assigned to me and i enquired them for the same. But got no reply. They just called me and said that you got failed to do the work and you have to pay fine for the same otherwise a case will be filed against you. I refused to do so. Then after some days, i suddenly got the mail from "adv. Puneet gupta" ([protected], [protected]) asking me that a case has been filed against you. I called him and he said that 'he is only concerned about money'. He asked to pay 9800, otherwise a case will be filed in aurangabad, maharastra. Even after paying this amount, they refused to give us any details of company and their organizer. Now, they are not attending my call.
