Do I need to bear the responsibility for charging the wrong power due to the wrong operation of the property management personnel?

You don't have to bear the responsibility for the wrong charge of electricity by the property personnel!

The property management company shall bear the electricity charges generated. Because the tenant has paid the property management fee to the property management company, the property management company should provide quality services for the tenant. However, due to the mistakes of the staff of the property management company, the electricity charges caused by the mistakes should be borne by the property management company rather than the non-residents. Property companies can investigate the responsibility of property personnel according to their own management regulations.
