None of the forums would be able to help with a locked account. You'd need to read the email that was sent in order to know what to do about it. The only other option would be to call our Billing Department.
Billing representatives are on hand to take your call between 8am to 8pm Pacific Time, 7 days a week at 1-800-59-BLIZZARD (1-800-592-5499). Customers in Australia should call 1-800-041-378.
When you first call, you'll probably get a recording that all of the representatives are busy and that you should call back. We suggest you keep redialing until you get into the actual queue, after which you'll have to wait for a representative to come on the line.
Technical Support is available
7 days a week, 8am-8pm Pacific Time
I'm not available Saturday/Sunday
