Sphere Services — online job fraud

I am a student and i was looking for a part time data entry job. I applied online and got a call regarding data entry job without any investment. When i inquired about the work they told me i need to send my aadhar card photo and accept thier terms and condition for the job. I wanted a jib so i did so. But after getting the file they had sent me i found that there were many grammatical and spelling mistakes in the file and also the text was poorly visible. The text was in Cursive font which made it more problamatic. Before the job they had told me that i would be getting assistance . When i tried to contact them, the didn't gave a proper reply. Hence i stopped the work because they had told me that if the work will not be 90% correct, i won't get paid. Then i inquired about this company online and i got to know that it's a fraud company and even if you submit the work, they tell that it is not 90% accurate and as you have not completed the work, be ready to face legal actions. Now they are threatning me of legal action. I feel trapped now. My life has turned to be a torture. Somebody please help me. Please...
