[Resolved]  Sphere Services — home based job scam

From the last few days i was free and i wanted to do some part time work from home. And i dont know from which site they found my mail id and they eend me a mail regarding their work. And it seems genuine they said you have to complete 150 pages in 15 days after that you will get your qc report and then if there is no mistake we will pay you other wise you have to pay the amount that is 6000 somthing. After after submitting my work they call me and said you had not upto 90% accuracy your id is been terminated. Now you have to pay 10500. And then they call msg send emails from many different numbers. They are harassing me. They are saying if you will not pay the amount then section this and that will set for you., and arrest warrent and all of that. I am a student and i really got mental pressure. I seriously wanted to get out of this.
