How long will battle.net account be down for maintenance?

i want to create a trial so i can RaF for wow to tripple exp my shaman but i cant bc the account is having maintenance and has been for about an hour and 30 minnutes. I called blizzard but wwouldnt talk to me because the computer phone told me their not accepting calls due to an (Unforseen emergency issue?) what the hell?|||Haha I recently just got SC2 on September 10th. I go to Create and Account and it says its down for maintenance. I have no idea what is going on. Should I worry?|||give it an hour, they're usually pretty good with fixing problems quick... on the other hand sometimes 12 hour maintainance lasts 24.... damn you blizzard
