Elevator maintenance is not timely, where can I complain?

Nonsense upstairs. I also do maintenance.

First of all, it is stipulated that it should be repaired within half an hour (if this is the contract for the maintenance unit and property stipulated by the Technical Supervision Bureau, it may be 20 minutes or 15 minutes, usually within 1 hour). If the factory maintenance worker lives in a residential area, the length of time to go to the scene to repair the elevator fault within 30 minutes is certain, depending on the elevator fault.

If you complain, then find a property complaint or a neighborhood Committee. If maintenance workers are often irresponsible.

Then call the technical supervision bureau directly to complain about the maintenance unit that the technical supervision bureau will inspect.

But in the end, I suggested not to complain (technical supervision bureau) because it is not easy for maintenance workers to make ends meet. The problems of general maintenance units are scattered, and then maintenance workers run around, and a few are irresponsible.

Personally, I suggest changing the maintenance unit.
