Captcha — fake job

On 19th july a call came and they gave me a captcha filling job . they took my adhar card photo and made me sign on an agreement digitally. later they called for an confirmation call and said that if I don't fill 9000 captcha correctly in 10 days they will charge me ₹5000 as penalty as per the agreement. I started the job one day later then as i was typing after every 150 captcha i filled the count get reset to zero . i have filled more than 1500 captcha still it is showing zero. now after reading in Google about other people's article i came to know it is a scam and however i type they will take 5000 from me or else file a case against me . i am a poor student completing my final year. i can't pay 5000 as i don't have that Much cash and neither can i afford a case as this will hamper my chances of getting job in upcoming campussing. i called them about this and they are saying u Just fill captcha. but if i don't know how Much i have filled or how many are correct how can i know how many are remaining. they are not helping and as i have understood they will charge me 5000 soon

please help me get rid of the scam I can't pay that much amount. its a fraud company taking advantage of innocent people. please help me and take action against them so that they can't thug any other innocent
