Inetwork — captcha company

My name is Senjyoti Howlader. I am a student. I was finding home based jobs so that I can have extra money. I got a call from a lady, Kriti Shah, who offered me the job and said that I have to fill captchas and if I do 90% correct captchas, I'll be paid and from my salary they would cut Rs 5000/-. I agreed to the job offer and they asked my ID Details and asked my e-signature for the contract purpose. Later, they sent me the contract on a RS. 100 non judicial stamp paper.
After I have started the work, I noticed after doing 150+ captchas or sometimes 120 captchas, the no. starts from 1 again and further the session no. changes drastically e.g sometimes it is 15 and the next time I am opening the app, the no. changed to 23.
I asked the company through their helpline id and they started saying that the company does it.
Then gradually I started noticing that there are more no. of wrong captchas than I actually made. Further, there are less no. of captchas enlisted. When I asked them about it, they kept replying that "it is not manually counted".
Now i have been called by their advocate Mr. Rajesh Trivedi ([protected]) that I have to submit Rs 5000/- before 4pm or else my file would be submitted in the court and legal proceedings would start.

Please Help.
