Symfony 3 - Vous avez demandé un service inexistant me rend fou

Ok, donc ce n'est pas la première fois que je suis de la création du service mais je ne peux pas résoudre l'erreur

Vous avez demandé inexistante de service "global_settings".

Étapes que j'ai pris pour assurer le service est correctement configuré

Mon AppBundleExtension.php

namespace AppBundle\DependencyInjection;

use Symfony\Component\Config\FileLocator;
use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\DependencyInjection\Extension\Extension;
use Symfony\Component\DependencyInjection\Loader;

class AppBundleExtension extends Extension
{
    public function load(array $configs, ContainerBuilder $container)
    {
        $configuration = new Configuration();
        $config = $this->processConfiguration($configuration, $configs);

        $loader = new Loader\XmlFileLoader($container, new FileLocator(__DIR__.'/../Resources/config'));
        $loader->load('settings.xml');
    }
}

Mon settings.xml

<?xml version="1.0" encoding="UTF-8" ?>
<container
        xmlns="http://symfony.com/schema/dic/services"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd">
    <services>
        <service id="global_settings" class="AppBundle\Services\GlobalSettings">
            <call method="setEntityManager">
                <argument type="service" id="doctrine.orm.default_entity_manager" />
            </call>
        </service>
    </services>
</container>

Mon GlobalSettings service

namespace AppBundle\Services;
use Doctrine\ORM\EntityManager;
use Doctrine\ORM\EntityRepository;
class GlobalSettings
{
/**
* @var EntityManager
*/
protected $em;
/**
* @var EntityRepository
*/
protected $repo;
public function setEntityManager(EntityManager $em) {
$this->em = $em;
$this->repo = null;
}
/**
* @return array with name => value
*/
public function all() {
return $this->$this->getRepo()->findAll();
}
/**
* @param string $name Name of the setting.
* @return string|null Value of the setting.
* @throws \RuntimeException If the setting is not defined.
*/
public function get($name) {
$setting = $this->$this->getRepo()->findOneBy(array(
'name' => $name,
));
if ($setting === null) {
throw $this->createNotFoundException($name);
}
return $setting->getValue();
}
/**
* @param string $name Name of the setting to update.
* @param string|null $value New value for the setting.
* @throws \RuntimeException If the setting is not defined.
*/
public function set($name, $value) {
$setting = $this->$this->getRepo()->findOneBy(array(
'name' => $name,
));
if ($setting === null) {
throw $this->createNotFoundException($name);
}
$setting->setValue($value);
$this->em->flush($setting);
}
/**
* @return EntityRepository
*/
protected function getRepo() {
if ($this->repo === null) {
$this->repo = $this->em->getRepository('AppBundle:Settings');
}
return $this->repo;
}
/**
* @param string $name Name of the setting.
* @return \RuntimeException
*/
protected function createNotFoundException($name) {
return new \RuntimeException(sprintf('Setting "%s" couldn\'t be found.', $name));
}
}

Puis à l'intérieur de mon contrôleur, je suis en train de faire est de tenter d'accéder au service en utilisant le code suivant

$data = $this->get('global_settings')->get('paypal_email');

Ce que je fais mal? Toute aide sera vraiment apprécier comme je suis de toutes les idées.
