If you cannot come to terms with an official finder (www.hamburg.de/behoerdenfinder/), just calm down please and try this one: the "Bürger-Navi".
Treat it as a guessing game: „What is my problem ?“.
If you win, you will know how to call your problem in the official German language and how you could solve it.
Of course, the city hall is responsible for the final solution.
...trying is more important than studying(*):
