What to do if someone pretending to be from a utility company knocks on your door.

Utility impostor scams can happen any time of year, but are especially common during extremely cold or hot weather when people can't go without their heat or air conditioning. In a utility impostor scam, a scammer impersonates an electric, water, or gas company representative. They may call you on the phone, send an email, or even knock on your door in a realistic-looking work uniform, claiming you have an overdue bill and need to pay immediately to prevent your service from being shut off.
