Why they don't have an issue report form for the beta drivers I'm not sure, but beta software in general might cause you trouble... that's why it's still called beta software. If you've still got problems when using the 13.1 driver, then just report that instead.
I'm just a wielder of the Ban Hammer of Doom here on the forums... no idea if there's activity about this going on at AMD internally.
Sometimes getting the run around is standard practice on these sort of things, especially when one of the parties involved is having to give away free products because of a botched product launch...
