Crystal Hi-tech Solution — I'm complaining for forcing to pay amount

I got a form filling job from CRYSTAL HI-TECH SOLUTION company situated in Gujarat, they asked to fill 800 forms in 10 days, with minimum 90% accuracy, I don't complete the task because of I can't log in the link they send to me. and I informed that person contacts me but they don't respond to me. After a few days, they informed me paid the amount of penalty and they informed to 2 different company and also 2 different legal officers so I trust in that time. Today they call me to pay the amount within half an hour I say them I pay the amount in one week they shouted me to pay the amount today itself
