Kdt Company — they asking me to pay money 5000 rs

Address:

Maharashtra

I am m. Durga devi.in order to earn some part-time money, i got myself registered with kdt company for captcha filling work. I applied to them through quiker jobs. They got me into an agreement (1st page attached) as per which i had to submit the work within 10 days with 90% accuracy, failing to which i have to pay the penalty amount of rs.5000 which they didn`t ask to pay beforehand. The work was supposed to be done through an app (Mac2cap) by logging in and filling the captchas. Their app sometimes freezes and sometimes doesn`t count the filled captchas. I also encountered the difficulty in recognizing the difference between small l alphabet (L) and capital i alphabet (I). So, i asked the concerned person over their whatsapp number but received no help in the matter. Now, they didn`t inform me before and when my 10 days got over they start sending me threatening messages and emails via. Their advocate associate, sudhakar. He's informed me that a case has been registered against me. They are calling innumerable times in a day and asking for money. Kindly help.
Please help me. They are torturing me mentally. Please help me
