The relevant organs of the power supply bureau include the discipline inspection and supervision office, the legal affairs center and the logistics center, which are responsible for the supervision of power supply services, and can directly call the relevant organs of the power supply bureau to make complaints.
You can also complain or report the work style of power supply workers and the phenomenon of power interruption by telephone, internet, SMS and email.
If the power supply bureau causes damage to users, it is also obliged to compensate. If the complaint problem has not been solved, it can be solved through prosecution.
To be on the safe side, I suggest that you can hire a lawyer and give necessary assistance when necessary.
