Online Form filling job

Sir I have applied for an online data entry job on the internet from the web page called wap.clickindia.com and I got a call from ACL enterprise Surat Gujarat saying that they will provide form filling job and provide a salary of Rs 20,000/- with all the cuttings I will get 15,000 per week which sounded very interesting...so they sent me an online agreement in which the content in it was not viewable and they told me to sign it from my mobile itself...after I signed the document I downloaded and it was a blank document, but still I stupendously proceeded to do the work which was to complete 800 forms in 7 days per form it was Rs 25/- it was an online website..they gave me a username and a password to login and do the form filling work I logged in and completed 191 forms and my mom's told to check if it is a legal company or not....so I went on browsing for the company but I couldn't find anything...then I browsed about the web link they gave me to do the work and I found 2 complaints in the web about the website saying they are fraud and they say that we breached the contract and ask for money by threating messages....so I was frightened and I texted the person via what's app that is it fake company? And he said that is some other company and then I texted him back that it is fraud and blocked him because I was working for earning money and in return why can they ask again...and after 2 weeks this day a girl called me and said that you have not completed the work and sent me some legal kind of documents with my name on them and told me to pay Rs 50,000/- via Paytm or Online/ NEFT...they called me from GS solutions today and threatened me by what's app messages to pay...so I again searched about GS solutions in the web and I found about 4 to 5 complaints that they are fake or fraud company and they always ask for money but no one of them has been paid...for Registration purpose I have given them my Aadhar card number....What should I do to them? I donno if they real or fake...I believe they are 95% fake!
