I Tech — harassing to pay money

Address: New Khirdi Road, Aurangabad

I got a job through quicker for typing 10000 captchas in 10 days. I applied for the same. One of the person has contacted me. The person who contacted me told that i have to complete the 10000 captchas in 10 days. I said okk. He said that i will get the verification call and said to say i am ready to proceed. But in the verification call, that lady told me that if i could not complete the work i have to pay ₹5000. After the verification call, i contacted that person and told that if i could not complete she said to pay ₹5000. He responded me, it doesnot matter mam and it is only the formality. They asked for my aadhar card photo and gave the same. Then they told to download an app through the link they send. Then they told to upload my picture and signature. And i uploaded also. Also they have send an agreement afterwards about the rules of typing captcha and in that it was written that if we didn't complete our work or if we don't have 90% accuracy, then we have to pay the penalty. And in that it was mentioned that it is a contract base, they did not say about this. After that i started to type captchas. And everytime i typed about 160 captchas it goes back to 1. I enquired about that to them and they told don't care about it, but till the end of the day the count will be updated. Then i started to type again.# one of the legal advisor has emailed me that to pay the money around ₹8510 (₹5000 penalty amount + ₹3510 legal charges). They are threatening me to pay the amount, if i could not pay the amount they would file a case and move to the court. I was trying to contact that person who contacted me about this job, but he is not responding to my calls. They are going on messaging me please help.
