Note that these contact numbers and addresses specifically come from the
Ebook Library website, linked to from Ebook Corporations contacts page:
http://www.ebookscorporation.com/ebooks_contact.html
who run/own ebooks.com.
However, you will also note that, though the Western Australia address is the same on both sites, the US address differs, and the others aren't shared on both sites, so I couldn't say what success you would have with any number other than the Western Australia one, which, assuming you're OS, you might not be prepared to call.
Like I suggested earlier, 6 hours is probably not long enough to wait when it was the middle of the night in the place the support desk may be located, but hopefully, since a full work day has now passed here in Oz, you have since received assistance from them.
Cheers,
Marc
