Prospexiv — harassing on phone by demanding money and scarring of court case

I joined online form Filling job in the company named Prospexiv in Jan 3, 2019. They had got signed an agreement online. In that agreement it was mentioned that i have to fill 1200 forms in 12 days with at least 91.6% accuracy failing which I have to pay them registration penalty of 4650. I completed my work in 10 days, but when QC report was generated it showed that my work was not succeeded. I received a call from Fraud and fake advocate Suraj Patel saying that I have to pay registration penalty of 4650 otherwise a case will be registered against me. He also emailed the same. I then agreed to pay the penalty and I paid the amount. After then I again received a call from that company saying that agreement was of 11 months contract and if i want to get this agreement terminated then I have to pay 6560 rs more to issue the noc and thus to terminate the agreement. Again I agreed and paid the same. Then I was given an email which showed that all my dues are cleared and I am free from company and all the legal proceedings. After 1 month that is in Feb 2019 I again got a call from the company to pay more. That time I refused to pay and scolded that man. Then after 2 months that is on 27 April 2019 onwards again these people are harassing me continuously to pay again otherwise the case will be registered against me and arrest warrant will be issued against me. I am trying to call fraud advocate Suraj Patel and Shweta Patel who got me registered with this company but now their mobile nos are coming out to be invalid. Please help me out otherwise I will definitely die because of these fraud company and fraud people.
