Type Jobs — complain for the fraud

I got call from this company that they are providing freelancer job, so i yes i am interested to do.
They said they will give me some form filing job.
They asked to fill 800pages of forms within 7days, than i got call from them that if i will not complete work within given time i have to pay penalty of rs.4000, so on same day i send them email that i am not interested to do work with you, even i not started work with them but still they are asking me for penalty of rs.4000. I dont want to continue this process. Kindly help me i am really worried as i am a college student i cant pay this much money to any scammer. And what if they send any documents at homes address. Tell me what to do... Please...
