Today I received a registered letter certifying that on 11 June this year I did a damage of 1974 euros and they want me to pay.
There is only one fact: I was absent that day. I took a permit to go to Gay Pride (I didn't specify this when I asked for permission). Now I've submitted all the data I needed to prove I wasn't there that day, and trust me, I'm willing to go legal if need be.
