I Network — fraud/cheating

I got a call 18/5/2019 from i network to work on app which involved entering 10000 captcha within 10 days and in which 90% has to be correct. When i accepted the job, they asked me to send my adhar card and mobile number on a whatsapp number, i don't remember their mobile number and when i had sent it, they had sent me two links, one of which opened to an app and they asked me to upload my signature on it. Then they filed an agreement without my permission and i got a mail from the company that if i fail to complete the work or fail to achieve accuracy then i have to pay rs 5000 penalty amount to company. I also got user id and password to login. When i started working on it they had not given me my work report when i was typing captcha they told that they will send it in the evening. But not responded when i calied and mail on company helpline to cancel my agreement and after 10 months i. E., 18/5/2019 to 27/2/2020 they are silent and today you are calling me to pay 7200 as a penalty how can i pay without any intimation and how can i trust you that you are a lawyer from that company only. This job is 100% fraud.
