1. Contact the developer: First, you can contact the developer to find out the specific plan and progress of resuming work. Ask them if they have any problems or difficulties and what measures they are taking to solve them.
2. Secondly, complain to the relevant departments: If the developer does not give a satisfactory answer, he can complain to the local housing and urban-rural construction department, real estate management department or consumer rights protection department. They will investigate the matter and take necessary measures to protect the rights and interests of consumers.
3. Finally, seek legal aid: If you think your rights and interests have been infringed, you can seek legal aid to solve the problem through legal channels. You can consult a lawyer or legal aid agency to find out your rights and available legal channels.
