The intercom at the entrance of the building is broken. Where can I fix it?

The intercom doorbell is broken, so you can find property maintenance.

If public facilities are damaged, the daily maintenance cost of public facilities is included in the property fee.

The intercom doorbell is a common part of the community, and the property is responsible for maintenance according to the property management regulations.

If the property is not well maintained, complain to the premises bureau.
