Threatning to pay money under breach of contract

I have searched jobs in quicker app I found some online home based typing jobs .I have applied for few of the jobs. On 13 January 2020 I got a text message teena joshi([deleted]/mail: [deleted]) from company INFONEX Gujarat (i.e) it’s a simple captcha typing work you can do in mobile phone max it will take 1 hour you can do any where there is only days limit no registration fee .Total 10000 captcha in 10 days in that 90% should be correct i.e 9000 should be correct .After then they asked my aadhar proof and asked to sign digitally in software agreement with photo, in that agreement they have mentioned that if I have failed to reach that I have to pay the amount of 9400 as penalty and also mentioned if I refuse to pay the amount they will proceed legally. I have signed it and I got mail from infonex regarding login id and password and also rules and regulations, I have started doing work from January 14, 2020 in mac2cap.apk .while I was doing that the count of captcha was clearing to 0 after typing 150or170 captcha I made a complaint to teena joshi(my representative from infonex) she said it’s fine continue your work and I asked how can check how many I have cleared she told it will reflect in the app after 24 hours. I have checked the application next day (i.e) january 15 2020, I have done778 in one day and in that I have done 448 wrong captcha. Then came to know that they are doing some misleneous work from server side in the application and while I was doing the work I have noticed that in captcha they are giving in wrong way of data like in behalf of I it is showing I and o and0 .so next day January 16, 2020 I have complained to teena joshi that it is not correct I want to quit the work and she replied if you have any query about quitting the work call to helpline number mentioned in the mail. I made a call to them they said no sir u have to complete the work and they said after the completion of duration our work submission team will call you speak to them and I waited for the call. I got the call on January 24 2020 from patel surbhi([deleted]/mail:[deleted]) another team from infonex regarding submission of work and they asked me to pay 9400 as I did not completed the work , but I requested them that I am a student I can’t pay that amount so please cancel my id from infonex and clear the data from your side, then first patel surbhi said no I cannot help company will proceed legally and then after she said ok but I have to pay 9400 as a penalty so that they will cancel the agreement and give the noc to me and further I will not get any issue from them, and she said that amount should be paid on the same day that too before 5 (i.e) January 24 2020 , so I said ok I will pay 9400 but make sure I will not get any problem from your side then she said ok then she texted me the bank details, next day i got mail from comapny associate advocate shreyass aggarwall that i need to pay money or they will proceed legally.
