Oc Technology — Harassing me as I didn't worked for them.

GUJRAT

I have registered my number on quicker to get some job. Next they i got a call from this company and they told me to the work online and they will pay 10000 in 10 days only. It was a captcha work. Firstly they gave me a demo so it looked easy and i agreed. Later on they sent a email id and password of their app to work upon it. But it was not opening later on i also complained about it but they didn't do anything. I shared it to my friend and he reminded me that ut may be a fraud company so i searched on google and i found many persons have complained about it. So i decided not to work for them. But now after 10 days they have sent a legal notice to me that they have filed a complain against me and they will end it only after i will pay the fine to them as registration fine.
I am very disturbed. Please help me.
