Pxv Captcha — fraud and threat call

Sir /mam,
My name is arjun, i am from jaipur. I searched in google for online job. One day i got a job from pxv company mentioning the job details. They told me that i have to fill 10000 captchas within 10 days and i will get salary 22500 and from my first salary they will take 5000rs as registration fee and asked my identity card for verification and they send me an agreement. But i felt something wrong so i just ignored it. Then they again called me many times and convinced me. They said first day is my extra day and works starts at 6pm but i got the work at 10.30pm and my session no was 2. Some characters in captcha were look alike so i asked them about that, they told me to zoom it, but it was unable to zoom. Next day i again asked for an example but they didn't respond. So i called them and they told me cancel captcha which cant identity, it was 3rd day and and my session no was 4. So i again send a mail regarding my doubt they didn't respond too. I felt wrong and i again gave 2 mails mentioning their faults and my loss of faith in them but they didn't. Yesterday they asking why i didn't complete the work but he was not interested to hear and told me to mail the problems but he too didn't replied for my mail. Then yesterday he called me and told to pay 5000 rs. These are misguieded me from sent a demo image with the symbols. Please help me and resolve this issue.
