In my design i have non standard billing fields label and markup. For example \"Town / City *\" should be \"Province *\".

I have used WOO documentation, and filter <

In specific cases you need to use the woocommerce_default_address_fields filter. This filter is applied to all billing and shipping default fields:
'country', 'first_name', 'last_name', 'company', 'address_1', 'address_2', 'city', 'state' or 'postcode'.

Here we only use 'city' and 'postcode' as in your code:

add_filter( 'woocommerce_default_address_fields' , 'override_default_address_fields' );
function override_default_address_fields( $address_fields ) {

    // @ for city
    $address_fields['city']['class'] = array('form-row-first');
    $address_fields['city']['label'] = __('Province', 'woocommerce');

    // @ for postcode
    $address_fields['postcode']['label'] = __('Zipcode', 'woocommerce');

    return $address_fields;
}

This is tested and working.

This code snippet goes on function.php file of your active child theme or theme
