There is something wrong with the elevator, regardless of the property, where can I complain?

It is necessary that there should be a walkie-talkie in the elevator to communicate with the outside world. Emergency lights and walkie-talkies are used to relieve passengers' mood in an emergency. When the elevator breaks down, stay inside and don't try to pry or kick the door, because that is the most dangerous. You just need to stay calm, ring the alarm or walkie-talkie, or see if there is a signal on your mobile phone, call an acquaintance and tell them. Then wait for the professionals to save you.

If the property management department is in charge, you can check the telephone number of the local quality supervision bureau and complain online. However, you have to warn the property to do this, or you will not get along well in the future.
