I rarely had this problem, but keep in mind, I was the "Greek bearing gifts" showing up with calendars, pens, CDs, etc..., often dressed in performance clothes. When I had an AD that ignored calls, I just showed up unannounced, usually around lunch time, with a package of goodies and my booking calendar. This usually resulted in me booking out the entire you with some egotistical, self-centered SOB that I had no contact with until the same time the following year.

All the best,
