Hi darkwolfsg,

I've merged your post with the main thread about the same error message: "This service is currently unavailable for this account. If you wish to purchase more cartel coins please call our Customer Service team or you can try again tomorrow."

As mentioned in my post above, you need to directly contact our support team by phone for this kind of issue.
