They hate people calling them. It's a terrible experience. They want you to do everything on their website, and go out of their way to make it difficult to contact them directly. Ryanair is notorious for charging for absolutely everything (Checkin fee? Seriously? Like you can opt out of that.)
There is still an "online checkin fee", which is lower than the "real life" checkin fee, but it's still there. I maintain you can't opt out of checking in when you fly.
