Recently, the community where I live often has power cuts and water cuts, and the property can't be managed. Where should I complain? Thank you for your advice.

First of all, make sure that the property right of power supply management in your place belongs to which unit. If it is directly managed by the power supply bureau, you can complain directly and call the power supply bureau to complain. If it is a high-voltage self-management household, it is generally the property management unit leader in your place or directly related to the complaint unit.
