I felt like checking out Starcraft 2 again today, but when I tried to log into my battle.net account, it kept telling me my password was invalid.
I tried to use password recovery, only to receive an error saying the email/name combination I'm using does not exist.
Queue an hour spent digging around the support section trying to start an account recovery process, only to find out my security questions have been changed and all my CD keys come up as invalid when I try to use them to prove account ownership.
There's literally no way I can find to contact support that doesn't already require account access, which is incredibly fucking stupid.
