Found this as a contact entry "ACCOUNTS" for (03) 9223 5592.
This reverse Australia was first entry when internet search.

However, it appears to be a preconfigured entry when you install a SIM card for ALDIMobile.

That specific number is not on the Aldimobile contact us

though is part of the 100 indial number range when you consider the Main line ends in 5590

but is mentioned by an astute in the Whirlpool forums.
