Who should I report if the property monitoring is broken?

Property. The owner is not responsible for the bad monitoring of the community and needs to report the property maintenance. After all, the monitoring is broken, things are left in the community, and the property can't monitor who stole them, which will have an impact on many aspects of the property. Property is a kind of trusteeship service, entrusted by developers to manage residential areas, such as buildings and public facilities.
