Usually, it’s the condominium administrator who has your direct contact, which is why they will be the one to communicate the problem to you. To ensure the situation is resolved, you should get in touch with the neighbour in question to understand what the problem is. Ask them to describe the situation in an email and to include photos and videos that show the damage caused. If you have someone who can go to the neighbour's house to assess the situation, it saves time and speeds up the resolution of the problem.
