Harassing and torturing in calls and messages

I was searching for a part time home based jobs in quikr application, then i get a call from jexmon solution, they told me home based work of captcha entry by android phone, pc.in which they will provide 10000 captcha entry and we have to complete with 10days and 90%accuracy. They ask for my id proof and two mobile no. And i got a work agreement on my mail id. I got a user id and password which was not opened till 2 days and after two days again i got user id and password. When i statrted the entry there was no display of our entry how much captcha entry i have done. I realized that this company is a fraud and they will not give us any payment they will only got payment as penalty from us. I talked to company and send them email for cancellation of agreement. They were forcing me to do work and pay panalty amount 5000/-. Now they are threatening me as that they have filed a case against me for a settlement to the company of rs 5000 under section 420 and 37 of the indian panel code, whereas i have not sign in agreement. Jexmon solution is a fraud company who are only charge rupees from us. They are bothering me and mentally tortured me. I request you to kindly take the legal action against this unregistered and fraud company.
