The door of the corridor unit is broken. Want to know whether the owner of the property or the unit should chip in to repair it? Where can I complain if the property is not repaired?

The corridor unit door belongs to the owner of the * * * unit and has facilities, so the owner of the * * * unit should bear the maintenance costs. The most complicated problem is not to repair the door, but to collect these maintenance fees from door to door. If the property is forced to bear the maintenance costs. When I went to the State Council, nobody accepted my complaint.
