Service is non-existant? Symfony 2 - symfony

Question

I'm trying to get this simple notification service working and I am having no joy at all. I've never used services in symfony before so I could be overlooking something pretty basic, however it all seems correct to me so I'm kind of banging my head against a wall here.
I've included everything to do with the service, help would be really appreciated!

Answer 1

Based on your answer to my first comment, it would appear that your services are never being loaded due to not following the naming convention for your extension class.
If you have a GameMainBundle for your bundle then you should have GameMainExtension for your extension.
More info here: http://symfony.com/doc/current/cookbook/bundles/best_practices.html
You might still have some problems once you get services.yml loaded. Calling your service a controller is a bit non-standard. But see what happens.
