Pxv Captcha — job details

I had signed a contract in this company for doing captcha job but they didnot give me any job. Noew one person claiming to be advocate is asking for money for not doing the job. I need help please. I called the person who gave me about the job deatils but she said we had sent a mail and that she had confirmed with me through call that she had sent a mail and i told her ok and i will do the job. But i did not receive any call from her and neither i got any mail to do the job. How will i do the job if they dont provide me the user id and password. They are fraud company when i came to this forum only i found many complaints against them. I want a solution to my problem they are asking me to pay 6300rs and to confirm it by 2. P.
