The power grid staff didn't answer the phone.

If the grid worker calls you, it is usually a serious matter, so if you don't receive it, call him back and ask him what needs to be handled or solved. Or ask others if they are all right. Anyway, we should know as soon as possible and don't delay.

If the grid worker calls you and you don't receive it in time. Don't worry too much. Generally speaking, he will only call to ask about the situation, such as where you have been recently, or ask you something to fill out, so if you don't answer, he will send you a text message or call you when you are free. If you are really in a hurry, you can go to the community and ask yourself.
