Scams like these

[kookaburra75]

I saw a charge on my AmEx from ATOONLINE in Adelaide which I read as "A Toon Line". It took me a while to realise that I had not been scammed, but it was in fact "ATO online".

We've all been there one way or another with mis-read descriptions in our statements

As there were no attachments, I assume this was an email confirmation phishing expedition.
Not a place to start wandering
