Avi Enterprises — Demanding a amount as a reason to cancel agreement

Address:

AVI ENTERPRISES (2-A Ketan Park, Vapi Main Road, Gujarat.)

Sir/Mam,
During February month, I was looking for a parttime job, and then I get a call from this company.
They told me that write 10, 000 captchas in 10 days and per captcha, you get 3 Rs.
Month payment is 30, 000 and the registration fee is 6, 900 and they told if I fail to complete this target or there are more than 10% mistakes in captchas then, they will charge.
Also, they aks for aadhar card photo, Email id, and mobile number. I gave all of that. They mail me a contract with my name and address. After that, they told, "You will get a verification call and you have to say only yes". I said "Yes".
After all this procedure on the same day, they send a mail my ID and Password for the captcha filling app and said that you can start work from 6 Pm.
I installed the app and start working after filling about 500 to 600 captcha, I check the stats but there is nothing. I am getting depressed and contact a person from this company, he told me that after one day you get stats. The next day I check for the same but there is nothing in stats.
I search on google and get information as it is a fraud company on same day I contact a person and tell that, I don't want to work and can't get a reply from the person. I uninstalled the app and stop working.
After 10 to 15 days I get a call from this organization and they demanding an amount 6900 rs. I told that person I can't arrange this amount.
After some time on the same day, I get another call, He told me that he is a legal Advocate from Gujrat and you give this amount otherwise company registers a complaint in the police station and you get 14 days non-bailable warrant, the notice is send to your address. Also, you have to come Gujrat session court and pay 80, 000 rs. I told that I can't give the money. They call me again and again and tell me about legal rules.
Please help me in this.
