ok so if you have ever had to call blizzard right away and there is a long wait for the support line or you can't even get through heres what i have been using for years.
step1. what you do is call the technical support at 1-949-955-1382 once you get through to them (usually u can get through on the first call but lately because of WOLTK you may have to redial).
step 2. wait for the person to talk for a little and list the different numbers to press (about a couple of secs) then you can just press 1 for the automated support
step 3. once your in the automated support press 8 and then you have to listen to the person for a little
step 4. finally it will ask you to press 1 to be transferred to a live rep (these are the account reps not tech support)
step 5. you will get transferred right away and you can change the info before anyone else
