Siena Services — fraud and threat

Address:

Aurangabad, Maharashtra, Aurangabad, Maharashtra

I had registered myself on quikr for a part time job. One day I got a call from a girl Khushi Khan from Siena Services. She offered me the captcha filling work and offered a salary of Rs. 30, 000 at Rs.3 per correct captcha for 10, 000 captchas in 12 days with 90% accuracy . I completed the work but as per the report(I believe the report was forged) I was not able to achieve the accuracy mark and I was asked to pay Rs. 5, 000(mentioned in the agreement)as penalty or else I the company would be dorced to take legal actions. Out of fear I paid the money and later got an NOC from the company. Today I got a call saying that I have not closed the registration agreement and I need to pay Rs. 30, 100 for it or else legal action would be taken against me.
I also got a mail saying that I was given a legal notice but I didnot appear in the court (I did not receive any such legal notice) so now I have to pay either Rs. 30, 100 or they would be raching my home address.
The company is fraud.
I don't know what to do.
Please help me.
