Meta Box data not saving to post billing order details (woocommerce)

I have added a meta box to the order details page which pulls a list of users under the “courier” role. Now i just can’t get it to save the data to the post. Also, i want to add a column to the admin order page showing the selected name and lastly i need to pull this data when I export the rest of the order details. I hope I’m at least on the right path.

<?php
//create metabox
add_action( 'add_meta_boxes', 'add_courier_meta_boxes' );

function add_courier_meta_boxes()
{
    add_meta_box(
        'woocommerce-courier',
        __( 'Courier' ),
        'courier_meta',
        'shop_order',
        'side',
        'default'
    );
}
function courier_meta($post)
{
	wp_nonce_field( 'save_courier_meta', 'courier_meta_nonce' );
//get users by role

$args1 = array (
 'id' => '_Courier_Select',
 'role' => 'courier',
 'orderby' => 'user_nicename',
 'order' => 'ASC'
);

$couriers = get_users($args1);
echo '<select names= "Name">';
 foreach ($couriers as $user) {
 echo '<option name="_user" value="' . $couriers . '">' . $user->display_name.'</option>';
 }
echo '</select>';
}
// this section of code is suppose to save whats selected in the dropbox
add_action('save_post','save_courier_meta');

function save_courier_meta($post_id) {

	if ( ! isset( $_POST['courier_meta_nonce'] ) ) {
		return $post_id;
	}

	if ( ! wp_verify_nonce( $_POST['courier_meta_nonce'], 'save_courier_meta')) {
		return $post_id;
	}
	if ( ! current_user_can( 'edit_post' )){
		return $post_id;
	}

	update_post_meta( $post_id, '_Courier_Select');
}
