Symfony - Services stopped working, what to do?

Question

symfony

Good afternoon.
Updated composer update and services stopped working, and only in one bundle.
Symfony 2.6.6 Cleared the
cache.
Previously contacted the service, everything was fine, now it is not clear what the problem is.
$this->get('hash.service')->encode($code);

$this->container->get('hash.service')->encode($code);

Both options now issue

You have requested a non-existent service "hash.service".

Updated composer update and services stopped working

I wonder why this is ... See how your service is called in the very bundle in which the whole thing does not work and where the service disappeared. Try to write the version in composer.json as precisely as possible to allow only minor releases to be updated (no dev-master).
