The property is connected wrong.

1, whoever connects the wires when installing the meter is responsible.

It's legal to pay back the money, because you wired it wrong first, and the electricity belongs to the national grid, so you have to pay it back.

3, there is definitely no discount, this is not a shopping mall, and the electricity fee is set by the State Grid.

It is legal for the power bureau to stop your household appliances without making up the difference, because you owe money. In some areas, IC card prepaid meters are used, and you must pay in advance to use them. Once there is no money, the power will be cut off immediately.

5, the electricity bill is well documented, according to your usage, but you only use the sub-meter of the mother meter, and the degree of management is less, but the mother meter will not be less, so the power bureau collects your money according to the actual degree of the mother meter. You can also call the electric power bureau to check your actual degree.

6. See who is responsible for the wiring of your electric meter. If it is in the community, it is their responsibility. If it is power supply, it is their responsibility.

In short, whoever is wrong pays the bill.
