Dial-A-Psycho

I don't know what it is but lately I've had a few experiences with people who dial the wrong number. I get people who keep calling back, even though I've told them numerous times that they got the wrong number. Or when I tell them that so and so do not reside here, they ask me if I'm sure about that. Well, today, I get the most crazed lady ever. Within a time frame of 20 minutes, she must have called 8-10 times! The first few times, I tell her nicely that she just has the wrong number. The following times she asks if a Albert lives here and I tell her that there's no one by that name. She demands me to tell her what my name is and the names of all the people who live here, uhm yeah, I'm going to tell you all of that. A later call, she's gotten pissed off and demands me to tell her the address to the phone number. At this point, I'm ready to *69 her ass! I get a few moments of uninterrupted work done and the phone rings again, this time the moment I pick up, the same lady just automatically goes, "Oh I have the wrong number" so I hang up without even saying a word. Immediately she calls back and yells at me asking, "Why did you hang up right after I spoke?!?" Uhm lady, as if I wanted to have a conversation with you! So I slammed the phone down and luckily no more calls after that. Sheesh, what a freaking psycho! It's so nice seeing people with nothing better to do. What I don't understand is why people do not understand what "sorry, you have the wrong number" means. I could understand calling back a 2nd time but anything after that is just ridiculous.
