Formalities if I need to press charges

Hello everyone,

I don't want to start with the very long and boring story about how the Post... won't give me the parcels i sent to myself... I call it the surrealistic Scandinavian. It is however a very bad welcoming in this country, as all I can see right now, is just how square they are, and I just want to be done with my work and go back to France.
So I just need to know if anyone of you ever had to press charges I've never done that before, ever, but they are taking it too far here and I have no other option.
Do I have to go to the police? Or are there some sort of public servant offices like in France?
Thank you very much,
