Account locked due to suspicious activity

So I was playing my Wow account in America, everything worked fine.
Then I flew to Japan for school and I started up wow only to find out that my account has been locked.

I thought no big deal, I would understand, so I do a password reset. I thought this would fix this issue but it hasent. I have called blizzard and told them about my problem and they keep saying that there is nothing wrong with my account. No restrictions, no locks, no nothing.

I can play my SC2 account, but i have to change my password every time I turn off my computer. But my wow account is still locked.

Has anyone ever experiences this before? Have I been hacked in some weird way?
