The RAF program has been temporarily suspended while they revamp it.
It’s been a while since we’ve updated the Recruit-A-Friend program, but the time has come once again to close the doors for a bit and do a little remodeling. On Tuesday, October 15, we’ll be temporarily shutting down new Recruit-a-Friend sign-ups. Don’t worry though—the program will be back (and better than ever) before you know it.
While we don’t have an official date to share regarding the release of the updated Recruit-A-Friend (RAF) program, those whose accounts are already linked are not affected by this, and any unclaimed rewards will be redeemable once the program starts up again. You’ll also be happy to learn that the current reward will still be available when the Recruit-A-Friend program returns—in fact, players who participate in the upcoming program will have even more reward options available to them. We’ll have more details for you at a future point in time.

There are a number of posts on the Blizzard Official Forums that indicate there is a problem with the current promotion. If you signed up with the RAF program before it was temporarily shut down, here is some information regarding the current status of existing RAF participants

As stated about 5pm 11/6/2013 by Blizzard Rep Vrakthris:
The in-game benefits are currently off, this appears to be part of the process of upgrading the program and doesn't look like it will be able to be resolved independently of it that process. If that changes we'll be certain to pass it along.
We hope to have additional information available but we do not currently have a specific time outside of "soon". The best I can give you is it is not the "some time in the distant future" type soon.
