You may be having problems with your electricity but you are positive you paid the bill so it will be nice to have an emergency electrician come out in the middle of the night if you need them. To have something fixed right away, you need to find an electrician company that is open all night in case you need to make a phone call in the middle of the night.
If you live in an apartment complex, you have electricians that are on call in case you have an electrical problem that you need to have fixed right away. All you would have to do would be to ask your apartment complex for an emergency number for the maintenance workers in case you have a problem that you need fixed that cannot wait.
