Form Filling — form filling threats calls

I the person who called me was a woman named keny roy m. N. [protected]. She told me that i will receive an i. D. And password if i join and after that fill 900 forms in 9 days after submission of all filled forms they will send me qc report in which the number of correct and not correct forms will be mentioned. I will get 25 rupees for each correct form and i will have to make accuracy of 1100 correct forms then the registration amount of rupees 4600 will be deducted from my final payment of 22500rupees if i do not get the accuracy of 810 forms i will have to pay 4600 as registration fees. I joined they requested me for my id proof and i gave the photo of my driving license and passport sized photo they sent me an message on whatsapp containing link of an app for signing the agreement which i did. I received an email and filled all the forms on with 100% accuracy because i was checking my each filled form three times after filling so there were no chances of mistake. But in the qc report i found that there were more than forms were mistaken and red marked that i was not expecting at all. Regarding this i tried to tell their helpline numbers and the person who call me for joining but everybody's call is out of reach. I got a call from their advocate and he is forcing me to pay 4600 rupees otherwise he will go legally. Please help me

I need to pay amount??? Plz help me for ur reply
