Pretty much. I had to call Accounts & Billing to get it taken off. Quick enough to do once I got hold of someone, but I did have to wait an hour and a half to get through. And of course, they stripped all my characters, so now I get to wait a week for them to be restored. On the upside, I did get the core hound pup out of the deal.
Once everything is all sorted, though, I will be getting my own authenticator, because this is a massive pain in the ass to go through, even if Blizzard is pretty awesome about restoring hacked accts.
Every normal man must be tempted at times to spit on his hands, hoist the black flag, and begin to slit throats.
