Thank you for flagging.
There are so many scams doing the rounds at the moment, you can't be too careful. When we send our bill alerts, they're always addressed to the person as you know. The generic "hello" is defo an alarm bell. You did the right thing by highlighting to make other community members aware - many thanks again for that.
I have added a few links below for help dealing with scam threats for everyone's convenience..
