The Speed of Germans

Now I have been living here in Germany for soon four weeks, there’s a thing I’ve noticed about Germans; they take a lot of time to answer e-mails. At least this is the case in public/governmental offices.
I have written an e-mail and waited for about a week for the answer, nothing.  Then another through a “contact form” a few days ago. Nothing.
I mean, how hard can it be to write a fricking e-mail?! It shall be interesting to see how long this will actually take.
