The unit building is overturned and the property is not repaired.

According to China's Property Law, property management is the provider of property services, and its management scope includes the maintenance, maintenance and renewal of property facilities to ensure the normal operation of property services. If there is a problem with the facilities of the unit building and the property is not maintained, then the following ways can be considered to solve the problem:

1. Negotiate with the property management company: First, you can communicate and negotiate with the property management company, explain the specific situation of the problem in detail, and ask them to fix it as soon as possible. In the process of negotiation, you can provide relevant evidence, such as photos and videos, to explain the problem more convincingly. If the property owner can't solve it, you can ask them to provide a written explanation and keep the relevant evidence.

2. Complain about the property: If negotiation with the property fails, you can complain about the inaction of the property company to the relevant administrative organs or government departments so that they can intervene in the investigation and solve the problem. According to the management system in different regions, the specific complaint channels may be different. Specific complaint handling procedures can be consulted with relevant departments.

3. Seek legal aid: If the problem remains unresolved after consulting the complaint, you can consult a lawyer to find out whether there are legal ways to solve the problem. Lawyers can help you assess your legal responsibilities and the possibility of safeguarding rights, and help you take corresponding legal actions.

No matter which way you take, I suggest you stay rational and calm in the process of communication and consultation with the property management company, insist on safeguarding your legitimate rights and interests, and try to collect relevant evidence to support your claim.
