This is something that is coming up more and more often these days. In fact this blog comes up highly for some of those phrases since I published the Google adwords telephone numbers in may 2008. One thing to note here is that now you need to have your adwords account ref (top right of the screen inside adwords) to get through. Methinks they are filtering who they speak to and who has to go the long route!
Anyhow, if you need help, then try the telephone path, if not, here is a real good place to start for adwords help in some areas there will be a yellow ‘chat box’ on the screen, if it is there, then use it.
