Honest question: does this actually help you get what you're after faster? I've never been a call center agent, but I've worked closely enough with call centers to know that they are often divided up in to different skill sets. Even if the automated responses won't get you what you need (modern ones can do quite a lot!) and you really need to talk to a person, you still have to talk to the right person. (Or the right group, anyway.) My impression is if you mash '0' until someone picks they will just end up transferring you to the right group to handle your query and you might end up waiting longer overall.
