If you're talking about World of Warcraft, some of the trial restrictions will stay for a couple of days until the retail stuff kicks into full gear. More is explained in your email. If you continue to have problems, you'll want to call Billing in your region.
Our North American team will be unable to assist with billing and account issues for individuals outside of the supported areas. The supported regions for the North American release of World of Warcraft are the United States, Canada, Australia, New Zealand, Singapore, Thailand, Malaysia, Hong Kong, Macau, Mexico, Chile, and Argentina. For assistance please contact your regional support team.
