Word that conveys being absent from an appointment

Is there a word that conveys being absent from an appointment? The closest words I can think of are "ditch" and "dump," but both are rather informal. I want to say something along the lines of:

I went in the office at 3pm to meet Bob, but Bob ditched/dumped me.

I realize that it's perhaps more common to say, "Bob did not show up," but I want a stronger expression that connotes a willful act of neglect or carelessness.


Someone who missed an appointment is sometimes called a no-show.


If you want to condemn Bob because you know that he deliberately didn't show up for the scheduled appointment (Maybe he does that often), you could always say:

...but he blew me off.

He stood me up is what you'd say when someone makes a social date:

Stood Up (Ricky Nelson song)
(by Willis Dickerson and Erma Herrold)
Well, I've been waitin' ever since eight
Guess my baby's got another date
Stood up, broken-hearted, again

I'll bet she's out havin' a ball
Not even thinkin' of me at all
Stood up, broken-hearted, again
