[Resolved]  Flex Enterprise — providing fake form filling job

I applied for some work from home data entry jobs on quickr. Same day i started getting calls for such job offers. The name of the company was flex enterprise and they offered me a job of filling 1500 forms for 20 rs each i. E. A total of rs 30000/- in 10 days. They said that if i fail to get an accuracy less that 90%, then i'll not get any salary and i'll have to pay a registration amount of rs 4500. After i completed the work and submitted it, a qc report was generated which indicated that my accuracy in the work was less than 90%. When i checked the report and forms, if felt like there were mistakes that were purposefully made after my submission, because most of the mistakes were not mine. And then i got a mail from associate advocate shubham aggrawal saying that i have to pay the registration amount so they'll start the legal proceedings against me. Within an hour, i got a call from same advocate. The email had content saying that he has received a file from flex enterprice filing a complaint against me and since then they've been calling and messaging again and again to blackmail, because they have an agreement with my signature on it (Which they took by cheating like they took from other people). What should i do?
