Account Locked? anybody know what to do next?

Hi Guys,

Last night 6 of my accounts are locked. I don't receive any email from Blizzard. The log in error is 204.

And the auto unlock system of blizzard doesn't work.

What should I do to unlock my account or I just wait? Is there anybody who has this experiences can help me ?

Thank you!!
