Qns Enterprise — fraud form filling

I got a job offer from a fake form filling website called form filling. They did not have their company website and they asked me to enter forms in http://onlinetask.in/Customer/Default.aspx.They were using gmail ids for all communications, the agreement was that if i fail to submit the work, i will have to pay rs.5200 as the company maintenance fees. The work given to me seemed pretty simple and it was offering a handsome amount of ₹. 20000 in 10 days. I am sure that the company is fake because i am mail that provides me detail of your company still not responding me.. I will send you the contact details and you can assess it yourself. Am i liable for any legal action?
