Infonex Gujarat — blackmailing me to pay or they will file a case on me

Respected sir/madam
I am sachin nannapaneni, i applied for this captcha work in quickr and i got a whatsapp message from infonex company they asked to download mac2cap 'app' 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 9400 if you donot reach 90% accuracy. Without my permission, they have filed an agreement call not answering after agreement. Very irresponsible person not answer my phone after agrerment they shall not help me for working didnt count my captchas after 150 entries it will be zero count. I asked them for clarification but they didn't. If i quit in middle wanted to pay 9400. Please take quick action against them and resolve this issue quickly.
After completion of my deadline advocate with bar council number: dl/463/2012 called me and saying to pay the amount 9400 and telling me about case filling against of me.
Kindly take frequently action on my request
