Sphere Service From Surat, Gujarat — harassment

Sphere service from surat, gujarat fraud or not!
Let me tell you my story how i got stuck in this situation. I am a student from a very poor family. So i was always curious of doing part time job. And one day i received a call from an unknown number saying that i can do part time job by typing at home, but i don't know from where they got my number, and i didn't even contacted them. They said that i have applied it, and i also said "yes", because i often search job from internet, so i thought that i myself did it, but i was wrong. When i searched my browsing history again, i didn't find myself registered in their web site. But i have already told them "yes". So i also thought i better do it thinking that i could make some money as i'm very poor to continue my studies. So, i thought of typing from my friend's laptop, they explained to me that i should type only in notepad but they didn't tell me clearly about the penalty. And they also made me to made agreement without my full consent, they sent a link and when i clicked it, it straight away activated and agreed itself automatically before even i didn't finish reading. I started to doubt a little but luckily or unluckily i proceeded still and told them that i will do my best. First they sent me one page to make 150 pages without much errors as possible. I did it my best and submitted and waited for the qc report but they didn't sent me back. After that they send me another 150 pages to complete within only 50 days which was very difficult for a fresher like me. Still then i was trying my very best waking up early and staying up late at night. But instead of my hard labour and toil, i still made a mistake as a fresher. The page they sent also was not very clear, i strained my eyes alot. I also chat them, asked them about if i stop the work in between, and some more question but they didn't tell me about the penalty at that time, still then i hurried away again to my work. Finally after i submitted the work they sent the report saying that i have been terminated because i failed to achieved 90% accuracy because of some spelling mistakes. After that they started asking money, 7600 rupees saying that if i didn't pay the penalty, they will take legal action against me. I requested them to disqualify me for the work and free me from legal actions, but they said that they can't. They have sent me two bank accounts,
1. Spectrum technocrats (Sbi. Bank) and
2. Sphere service (Xcel network): sent by sourab shah.
