Giving an Earful of Unhappiness

I don't know what the rules and regulations are for construction in Munich, but it shouldn't be legal to start throwing around giant sheets of metal at 7 a.m. Sure, for many, the rude behavior wouldn't matter as most are up and running. But for me, my schedule is a bit different as I work usually at night - writing until 10 or 11 (or later), then trying to settle down with a bowl of cereal and Sex and the City until around 1 a.m. If only I knew who to call, and what to say, in German. I'd give them an earful of unhappiness.
