Hello,
The same thing happened to me. Back from holidays, I had a letter from my supplier telling to pay 50$ for disconnection fee.
I called my supplier and had to open a new account. They did not charge for the 50$ though.
Now I am receiving two letters a week from Energy Australia. However, it is not addressed to my name. So I am just returning them.
What should I do about that? Should I contact Energy Australia?
And how is it even possible that my account was cancelled and someone opened a new one? Can I call Energy Australia tomorrow and have them opening a new account for my neighbor without any sort of verification?
