To many password recovery attempts? Help!

Hey, I have a small problem, I keep forgetting my password to my 2nd account ^^
I did it again today, and I have been able to get it back with the Password Retrieval thing. But I got this message when I typed in my acc name and email:

Q u o t e:
This account has had too many password recovery attempts. Please contact billing support at http://eu.blizzard.com/support/article.xml?articleId=23210 to recover your password.

Does this mean that I have to call Blizzard to get it back, and will I have to do so forever?


Thanks in advance
