how do you find your way to work every day?

People are annoying me today. It's not even funny. Yeah I'm a little edgy after my last week but some people are just dumb. Here's my conversation with Saturn today:
Me: Hi, it's Candice phoning, you left a message saying my spoiler is ready and I need to book an appointment to put it on.
Saturn: Well I'll look that up for you and phone you back to book an appointment.
(Two Hours Later)
Saturn: Hi, we can't find your spoiler, they said they didn't do the colour match last time.
Me: I had it done a week ago and you phoned to say it was painted and ready and it had to be put on.
Saturn: I'll check into that and give you a call later.
(Two More Hours Later)
Saturn: Okay we have your spoiler here and it's painted. You can come in any time this week, when do you want to come in?
Me: Tomorrow would work great for me!
Saturn: Oh, we can't do tomorrow, we have too many people booked.
Me: Well how about the day after?
Saturn: No we can't do that either.
Me: Well any day this week isn't any day this week now is it? How about Thursday?
Saturn: Thursday is good.

Man, How does this person find their way to work every morning? This is just the tip of the iceberg for stupid Saturn problems. I don't know how that dealership just doesn't fall into the great abyss.

Then this stupid computer problem at work here is just insane. Of course they came on a Friday to install it. The friday I already told them 4 times that I wouldn't be there. Why would you book an install on a friday anyways? There's only a 50-50 chance that the person is going to be here. I was close to losing it on them too! I know I'm a little overtired and stressed but that doesn't make up for sheer stupidity.
