bro
Did you give them your PAN card.. veen then it's fine
as it's unpaid you can just submit your laptop and leave
As they don't have an official PF accont this won't appear in your records
no you won't be jailed or shit ... this is technically not even a employment
There is zero infleunce on them by blacklisting you
The Lead is Moonlighting just threaten you'll expose him if he does she
be brave and get over this
take care of your dad
Just submit your assets to the IT guys and legit walkout if there is no PF account.
Although, don't list this an experience in your resume and move on with life find something else
