That's wrong information:

On this page[1] nic.at states (under "Cancel a domain") that cancellations can be made by fax or letter.

Also on the "fax confirmation" PDF[2] it says in big letters: "Please send it by fax or scanned by e-mail to: ..."

Thanks for keeping me honest. To be frank, I went the route of ignoring them at first, thinking it was a scam. Then I had to settle.

The problem could be that they require a signature. And a scanned+emailed signature is not a valid signature under Austrian law (IIRC, IANAL, but I am from Austria).

But from the PDF file in the second link from the parent comment they say that they accept email, so I would just try to mail them.
