Csr — Job fraud

My cousin had applied for the job on naukri dot com she received a call
from a number regarding the job and at the end they asked for new
reference she gave my sisters number as my sister denied the job she told
them that her brother is interested in job and I talked to them they explained
job description that I have to fill captchas 10k captchas in 10 days for which
they will pay me 22500 out of which 4500 will be deducted as registration
charges they asked for my whatsapp number and on whatsapp they asked
me for identity proof I gave them my scooty license they told I will get an
email which I havent received yet for details and they asked me to record
self declairing and reading the provided script so I denied that so they video
called me recorded me in which I declared that I will do the job if I failed I
will the penalty and they asked me for reference and I gave them my
friends and before they call my friend I asked my friend about it and they
called him he didnt answered my friend told to search numbers on true
caller and they turned about to be job frauds and then I googled about it
and looks like they have fooled a lot of people before me so I am worried if
they will send me some legal notice if I didnt worked on it kindly look into
the matter my sister received number from [protected] my friend got call
from [protected] and I got whatsapp from [protected] please help me out
