Also, [since Symfony 3.4](https://symfony.com/doc/3.4/contributing/code/standards.html#service-naming-conventions), _A service name must be the same as the fully qualified class name (FQCN) of its class (e.g. App\EventSubscriber\UserSubscriber);_, which is clearly using camel case.

For anyone looking at this - have a look at https://github.com/drewm/mailchimp-api. It's not a symfony bundle, but it supports v3 and works fine.
