I had to call Blizz support for the first time in my 2 years ++ of WoW-ing due to a hacking about 4/5 days ago. Note that you will not need your CD Keys if you know the answer to your secret question. Was on hold for nearly 20 minutes but I guess the Diablo2/Warcraft theme music you listen to while waiting isn't that bad.

One thing tho, I had to call 101 and ask them to dial Blizz for me.. somehow couldn't dial +19 1800-592-5499 by myself directly, just keep getting an engaged tone and not Blizzard's IVR recording. This was from a TM home line by the way. Didn't try from mobile.
