Fraud company and Salary not provided

Hello, I have started working in a company in March 2018. I found that the company is a fraud business firm as it is making fake certificates for US based Indian people for their jobs. Clearly examining this: if a person named 'Prathyusha' is living in US on H1B visa, I have to talk to recruiter that I am prathyusha and I am a US citizen (they make fake US driving licences). Also the real Prathyusha might be young and a non technical person but I have to tell the vendor that I (Prathyusha) have 8 years of IT experience. I have to create fake LinkedIn id, gmail accounts, many resumes. Even for skype interview the real Prathyusha is just acting to talk but a technical person is talking using a software for female voice. If she gets selected she will get at least $40 per hour and company will get $20 per hour as I was talk to confirm the rate only or above $60 per hour on corp to corp(this company's payroll for that big company). Realising all this is wrong and lying is not what I can do, I tried completing my second month that is April 2018. On 30th April 2018 I called the one girl working this plant in my city, that I won't be able to continue what is the procedure. (as I need Final fulfilment letter from them). She said drop a mail on hr gmail id. I said do I need to come today also She said No let it be what will you do if you come. I have this call recording. I dropped email on 1st of May 2018. They tried to delete that company's gmail account but fortunately I have still access to it on my phone. I screenshot it and then sent it to hr email id though my personal gmail account. Once She received my call and I told her that I didn't receive my salary for the whole April month. She said you should have told 15 days prior. I said my offer letter doesn't say anything like that and if the time O called her, she would have mentioned that I need to stay for 15 days I'd have done that. She was quite and then said yes you will receive salary I am not declining you. I have this call recording as well. Now it's 25th May 2018. They aren't replying my email or call. I have also sent a final email for taking legal action but still they aren't afraid. I guess there's less honesty left in this world. I need your help please. I don't have money I need my wage. Also I don't want to get involve in whatever illegal they are doing. They may harm me with their money. Need your advice. Thank you.
