Dear legally full and final to be paid within 48 hour of your leaving the company along with service certificate.
it is very unfortunate what is happening with you.you may file case in civi;l court if falls under the category of
manager otherwise in labour court if comes under the category of workmen

Final settlement dues ,PF etc. Cannot be denied by the company.You can approach its grievance redressal cell or customer care if existing to get a written reply from the company for doing so. If they choose not to reply you can write to the company law board .Thereafter, you can approach the civil court by filing a suit against the company.
