You got JoLui's answer about it being over and done, and mine is not to open a can of worms. We both live in France and deal with French bureaucracy.
If your conscious is bothering you, set aside the equivalent that you would have paid, and dribble it out to donate to organizations dealing with big problems, or leave something in the churches you visit here in France, or the buskers, or Secours Popular or the Red Cross who make sweeps of the streets nightly to help whichever homeless need something to survive. If you are here July 13th, donate it at a firehouse where the firemens' ball is taking place. There's a lot of good use for the money. Pandora says to keep the lid on the box.
