Fraud in online home based data entry job

I was searching for home based online job . I got a call from a unknown number calling herself MxxxI kxxxxn . She said me to I have to pay nothing for registration fee Nd she will give me a data entry job Nd I have to fill 15000 forms with at least 90% accuracy . If I do that they will pay me RS. 20 for each form total 30,000 . I said ok then they sent me mail containing demo work . And they sent me a link of an agreement app I downloaded it and they said me to upload sign and photograph . After sometime they sent me an agreement containing my photo and sign I was shocked because it was without my approval . Now ,I knew they are fraud and I said kindly cancel my registration ,I don’t want to do this work then she said me to pay Rs. 4500 otherwise they charge a case against me . I am really scared because it could ruin my government job life please help me sir
