Just an update.
We eventually sent a fax to the number on the sheet Ryanair at the airport gave us. We claimed out of pocket expenses since we couldn't claim compensation (we arrived just under the 3 hours late).
Thought we were very reasonable, restrained even in our claim.
This was last Friday. seven days ago. At least we have proof of delivery chez Ryanair. Nada so far. Haven't forgotten it, Michael!!
