annoying call

Caller: Check Your Bill

Typical offshore outbound call centre. You hear the beep and then someone says "Hello "insert random name"... When you tell them that you're not the person they're looking for, they hang up. But they call again, and again, and again... If you call the number back it says it's Check My Bill, but they are always closed. A quick google search shows they are a scammer wanting to do an energy comparison or some other kind of "service". Don't give them any information.
