You can go to the local real estate administrative department for consultation, or you can call or email for consultation.

2. Get the contact information through the owners' committee. In the case that the property company cannot provide the contact information of the property manager, the owners' committee may have the contact information of the property manager. You can contact the owners' committee and ask if they can provide the contact information of the property manager.

3. Get contact information through other owners. If you know other owners, they may have the contact information of the property manager. You can try to contact them and ask if you can provide the contact information of the property manager.

4. Telephone consultation through the customer service of the property management company.
