How to Collect submitted data

Hi, I am using your free plugin. Facing bit problem in getting the submitted data. I have used your one of the hook to collect data but not working. May i know the hooks functionality is free or paid?
Here is my code :

add_action( 'vfb_confirmation', 'vfb_action_confirmation', 10, 4 );

function vfb_action_confirmation( $form_id, $entry_id ){
    //Perform some custom script
    echo "<pre>";
    print_r($_POST);
    die;
}

Not Working.
