Ryanair

I tried to book a flight from Girona to Eindhoven, all of the sudden I got a flight to Brussels? So now I fly to Holland for Christmas via Brussels and ow yes a day earlier then I putted in the online booking. The only weird thing is that this flight could not be selected on the website? Very weird.
And I almost forgot I checked around 21h for flights, and I booked at 23h and they were about €10 more expensive! How ridiculous?!
