If you mess with neighbors in the stairwell: to call a policeman, you must know what reference point to take your home.

This can be explained like this: you call the Affairs of the city (there is in any book on the first page. if you search the Internet), where you switch to ATC, and already at the Desk, you find out the address and phone number of your reference point to the police. If absolutely laziness - dial "02", call their street, house number and so you too can learn the phone number and address of your reference point.
Now do not rush. The police station is open from 9 to 21 hours. Employees work in two shifts. The first from 9 to 18, the second - from 14 to 21. But this division is rather conditional, may be from your precinct at that time, to which you agreed suddenly to happen in an emergency.
After you figure out which one of the inspectors serves your home, again you need to be prepared. First, clearly articulate what (who) you are complaining about. The statement it is better to make two copies. One you give the district on the second (this copy will remain with you) let them autograph it for the district. This is a precaution that if the officer carelessly will review your application (written in brief, clear,) and the noise from the neighbors or revelry in the hallway (from 23 to 7 am) will not stop, two not examined these statements, you can safely go to his superiors.
And another tip. One hundred and one wittingly or unwittingly, can hinder the local police to reach you. Faster you settle your case, if you come to him in a strong point themselves.
