Futurechase — Fraud online form filling and blackmailing

I am a Student living in Kerala. Recently I applied for home based job and got form filling from a company named FUTURECHASE.They offered me to fill 600 forms for Rs.18300 with 90% accuracy and if I failed to do so then I’ll be charged Rs.6700. I sincerely submitted the work with 100% accuracy. Today I received a mail from Advocate Mayur Joshi saying that I failed and need to pay them money. I had a web search regarding my problem and found that there are many consumer complaints regarding such companies offering online jobs. There are many people who got same threatening calls from the same person MAYUR JOSHI. They threatening me using their fake Contract. Please take initiative ASAP and prevent him further fooling innocent people who need jobs.
