Sc Technology — complaint about demands that are based on manipulated report

Address:

Aurangabad, Maharashtra

The company sc technology contacted me after my part time job searching on a website called clickindia. They asked me that if i am interested in doing a job of data entry which required me to write 12000 captcha in 12 days with 90% accuracy, that is if i completed writing minimum 10800 correct captcha in 12 days out of 12000 captcha i will get 2 rs. Per correct captcha. The fees for the
Registeration was 6000 rs which was to be deducted from my pay and if i failed to submit the required captcha or submitting captcha with less then 90% accuracy will require me to pay 6000 rs to them. I was desperate for a job so i said to them that i will do it and after that they said they will call again for confirmation and i will have to send a id proof on a given whatsapp no. I sent my id and they took my confirmation. Then they sent me a email with a contract with the instructions and guidelines.

Next day they sent me a email with instructions on what i will have to do which was to write captcha on a link where i will have to login by username and password that were sent to me later.

I started writing captcha on that user id from that day and i got a report of the written captcha next day in evening. The report shows accuracy of 86% that made me suspicious because i knew that i had written captcha with 90% accuracy.
So i thought maybe i made the mistakes and started writing captcha again but this time i also wrote the captcha down in a notebook so that i can check them again in the report, i did that for next two days and when the report came i checked the report which again shows a accuracy of 87.5% and 80%. When i checked the captcha in the report to my written captcha i found out that the report was fudged and manipulated so that the accuracy of 90% can never be achieved.
Next day i called the company helpline no. Which was given to me in email and told them to cancel my contract they told me to send an email about that which i did.
They responded with a email saying that i will have to deposit the 6000 rs. I again emailed them by saying that i have proof they are scamming me by showing a manipulated report due to which i will never be able to achieve 90% accuracy, they again responded with a same email and refused to cancel my contract and are threating to go through to legal means to get money. Please help me to get my contract cancelled as they are fraudsters who are scamming me to get the money.
I also checked online about their company and found that they did that with many people. Please help me.
