How to handle this call
Don't call back
You don't need to call back missed calls you don't recognize. If the matter is legitimate, the caller will ring again.
How to spot fake power-company calls
Legitimate power companies already know your account number and supply-point identification number. Don't engage with calls that push a switch without those details; verify with your provider's official desk.
