2. Report the problem to the neighborhood committee: If the property management company can't provide relevant information, you can also report the situation to the neighborhood committee in your neighborhood and ask them to help solve the problem. Neighborhood committees usually have a comprehensive understanding of the information of residents in the community and can help you obtain relevant information.
3. Find other ways: If none of the above methods can solve the problem, you can try to obtain relevant information through other ways. For example, ask neighbors or acquaintances for information, consult relevant documents or files, or consult relevant departments.
