1. Complaints about bribery and arbitrary charges involve legal responsibilities and must be supported by sufficient evidence. Without evidence, it is impossible to deal with them.
2. Complaining about service attitude. I suggest that you and other residents jointly write complaint materials, jointly sign and complain together.
3. Power supply maintenance. If the equipment belongs to the property right of the power enterprise (generally the equipment with a watt-hour meter or above), the electrician will go to the site for treatment at the latest 2 hours after your maintenance, which is publicly promised by the power enterprise. After this time, you can make a phone call to complain.
