Unless, they get back with you later and it was something they couldn't help,then no there's no excuse for that.
I had a friend who did that to me two times and like you I never invited them anywhere again no reason to.
The two times were quite far apart and we had been doing some things together in between.
After that though, I don't remember him ever asking me to do anything with him again and I didn't ask them.

@Mordechai 🤔if you are not planning to show for an arrangement to me common decency tells me let them know if you cannot make this

Why do you think they did that?
