QUANTIC SOFT SOLUTIONS (I NETWORK) - Blackmailing

My name is G Aravind. I just completed my Btech and in searching a job. I tried searching for data entry jobs from home. After one day of my search I received a call from I Network company offering a job for captcha filling. They also mentioned we have to reach **% accuracy or otherwise we have to pay the amount of *k rupees. I failed to reach the accuracy so I paid the amount of ***** initially. Two days later I received another call and asked me to pay ***** for agreement cancellation or ***** for continuing to work as secured deposit. I accepted to cancel the agreement and paid that ***** also and on that day those advocates told me that all your dues are completed and I received the NOC also from the company. Today one person called me and again asking ***** rupees for clearing cases against me
Please help me from this issue
