Phone Illiteracy

I don't get why people are so obviously dumb.

I'm thinking about this because not long ago I got a phone call. Didn't recognize the number but still answered. The conversations is as follows:

Me: Hello?
Lady: Hello?
Me: Yeah?
Lady: Is this 4304?
Me: No, 02.
>counfused pause<
Lady: Its not 4304?
Me: No.
>another pause<
Lady: Who is this?
Me: Katie.
Lady: Well I don't know you.
Me: Well, you have the wrong number.
Lady: I must.
Me: Yes.
Lady: Ok
Me: Ok. (Hangs up before she can respond)

Seriously. What the hell. I think I know my phone number woman! Why did it take three rounds for her to believe I wasn't who she wanted to talk to? I felt saying at one point, "No, this is really 5304. I'm just yanking your chain old woman."
Why? When I call a wrong number I don't question the other person! I say "Oh I'm sorry!" and hang up. People like that just dive me nuts. Some people are just really phone stupid. And it's happened to me before at home.

Me: Hello?
Lady: Is this Richardson's Butcher Shop? (ok so I don't remember the name exactly)
Me: No.
Lady: It isn't?
Me: No.
Lady: This isn't 7183?
Me: No it is 9183.
Lady: Oh.
Me: Yeah.
Lady: Well...*click*
I hung up on her, not gonna lie.

If I were working at said Butcher Shop, why would the lady think I'd deny it? I'd take her damn call and her damn order. I wouldn't blow her off. I just do not understand it.

My personal favorite is one from a few years back. I won't type out the dialogue but it consists of two girls calling my cell phone about three times asking for a person and even after I told them they had the wrong number the first time, they called back. So finally I just sent it to voice mail. And then they finally got it. Cuz I wasn't telling the truth before. It's like my voice mail was a shovel to their ditzy minds.

Ditzy Girl: (to her friend) Oh my god! Didn't he say this was his number?! It's like, some girl named Katie. That's weird!

I tell ya. Some people make me scared for the future. If they run the world then we're all fucked.
