Question

But she rejected his call with the words:

Mr. Addams, please stop calling. We do not know where they meet.

Why did she reject the phone call from him?

Answer 1

The TV was showing a daytime programme where someone was being interviewed with the question:

So your son was brainwashed by voodoo slave masters and forced to recruit others. Let's take a call.

The joke is that Addams was supposed be be interested in that spooky type of activity and was constantly calling for more information even though, in the real world, no-one would believe such an outrageous claim.
