You have to go through the first couple of menus and then you press 0 to get a person. You may still have to wait though since they are often busy.
In fact, it's always a good idea when you get a voice mail system to try to press zero, even if it's not listed as one of the options. It's often left open as a back door to a live person but of course they would rather that you use the automated system if you can, to lighten the workload of their staff.
