Works well when it works! But when it doesn't...

Flight cancelled on a Sunday as Dresden airport closed due to snow. I wanted to tell them and request collection from station as trains running. No response from either emergency no. Rang UK no., who couldn't get response either.
They now try to say snow a 'force majeure' so no refund payable. The only force majeure is that they provide no European emergency service at weekends, no snow in rest of Germany so that's not an excuse. Left me 50 out of pocket as had to pay for taxi from station - they were still running so purely Holiday Taxi appalling admin.
Very disappointing.
