Mac2Cap — fraud by the company

I got a call from a company o tech. Mac2cap 'app' captcha work... About a part-time job which involved entering 10000 captchas within 10 days in which 90% has to be correct and told that there are few vacancies left in this job. So, when i accepted the job, they had sent me two links, one of which opened to an app and they called me and asked to upload my photo and signature, aadhar card. Within a few minutes, i got a mail from them saying that you signed an agreement (Which i'm unaware of) that you are liable to pay 5000 inr in the event of not reaching 90% accuracy. Without my permission, they have filed an agreement call not answering after agreement.. Its my first day... Plzzz help sir
