Oc Technology — captcha fraud company

I applied for job in quickr. And soon got a message from them. They said to do captcha work. To complete 10000 captcha in 10 days with 90% accuracy. Other wise i have to pay 6700 as registration fee. They told me tat they are from government job offers. I gave my addhar card as identity proof. They gave me an app to do my work. But the app dont work, no matter how much i type it's always 1 and the app crashes. I cannot submit anything. I told them but they didn't reply in email/ whatsapp. I tried calling them but none of their number works. And my deadline is 10 days n today is day 2 and the app still dont work. They said they will take action against me if i refuse to pay in the contract that i never signed. I tried to investigate their company and found out that many people complained about a company name o tect (They presented same case as me) and many others in screenshot and paste it. I think they change the company name as oc technology... They are fooling others and mentally torturing people. They are complete fraud. I don't want others to go through the same. I told them i will quit since the app is not working, but they are not saying anything. I think they are waiting for the 10 day to be up, to ask for money or to sent notice. They have all my information i'm scared they will use it for bad purposes.

Based on my research they are completely fraud and changes their company name to lure people and now they are using the government name (So people might believe them). I fear that they will not stop, targetting people.

+[protected] this is the number that called me telling they work for the government. I have all their numbers.
