Resume Filling — Threatening

I got a message from company where they mentioned that we've got your number from shine.com then they registered my number and said you've to fill 600 resumes in 7 days . Being a student I was unable to fill this much resumes so I asked her for some more days she said you've to fill 1k for one day it's penalty. I said I've to resign and she asked me for 5900 now I've blocked all the number of the company but they are threatning me to file a complaint against me.
