Is there some sort of magic trick involved in getting a hold of chat support? Maybe a secret ritual? Do I need to make a sacrifice?

I've waited in Queue 4 times today and yesterday, for 2 and a half hours each time mind you, and each time I finally get to the front of the line it simply pops up "No agents available to talk to you." Are they just randomly closing my thing without any sort of notification? I don't get it. Super annoying.
