[Resolved]  O Tech — harassing me to pay money

Hello sir/ madam,
I got a call from o tech agent for the part time job, told about the captcha code filling work, that i have to fill 10000 captchas in 10 days with 90% accuracy and they have sent me 2 links to my whatsapp. They have asked me to send my aadhar card details, email id and my mobile number. After few minutes they said open that link and upload your photo and signature. I did the same.in the app, they have sent me the agreement without my permission. They did not tell anything about the agreement earlier. After completing the process i started doing the work. But they didnot update my work that how many captchas i have typed, and the app worked very slowly and app is always showing alert messages like"your app is not responding". I have complained about the issue and they didnot respond, they did not even take my calls. After 10 days, they started calling and sending emails and haradding and demanding me to 5000. Again after 2 days they called in the name og an advocate and blackmailed me to pay 13000, if not case will be filed aganist me and police will come and arrest me. They are demanding me money continously and sending me notice through email.
Please help me resolve this situation.
