WoW account already merged with battlenet???

I have to post this using my brother's account since I have no way of accessing mine right now... Here's the deal. I made an account way back, played for a while, then stopped. Today I bought myself a game card to get playing again. I log on to the site to add the prepaid card, and when I go to sign in using my user name, it tells me that I have to log in with the battle.net account that it is merged with. I stopped playing before this account merging business began...

Now, I understand that they are now merging the accounts, as I said I am on my brother's right now so I understand the process. But to my surprise, it has apparently already been done with my account. I have no way (that I have found so far) to see what battlenet account it has been merged with, and am quite perplexed...

When I log into my battle.net account, it shows my Starcraft 2, but no World of Warcraft. I requested a password reset for my WoW account which was sent to the email I use for my battle.net account, yet it is still not merged with it... I tried calling Blizzard, but the forty minute wait time just didn't work out... I sent them an email, but in the mean time...

Any ideas? Suggestions? Words of good faith? Jokes I've never heard before?

Send them this way...
