Autocomplete unpaid orders

Hi,

Customers can order free product vouchers on my site, so I removed payment:
add_filter( 'woocommerce_cart_needs_payment', '__return_false' );

And added autocomplete orders:

add_action( 'woocommerce_thankyou', 'custom_woocommerce_auto_complete_order', 9999 );
function custom_woocommerce_auto_complete_order( $order_id ) {
    if ( ! $order_id )
        return;

    $order = wc_get_order( $order_id );
    $order->update_status( 'completed' );
}

but the email to vendors is not sent.
It looks like the status is updated after firing the processing email.
Any idea how to fix this?

Kind regards,
Debby
