Hi sir /mam, i have also given the work that is 10000 captchas in 10 days eventhough i completed morethan 9000 captchas which is the minimum target for not paying penalty as said by them... I received a phone call from a lady mentioning herself as an advocate (who cannot talk in english fluently) asked and blackmailed me to pay 7600 rupees telling that three conpany will file a case on me... I paid the amount but they are now saying that i should continue the work if not i should pay 76000 rupees and i neglected and blocked their calls but they are constantly reaching and sending the pdf of legal notice as per some acts and messaged me that the hard copy will reach to my address within few days... Please Help me to get out of this scam... What should i do now??
