How do you feel when a sorority/fraternity cancels a mixer?

This has happened to us several times this past semester and it really upset us. The only thing that I can think of doing is to give the fraternity you missed the mixer with specific dates that they can use and if they say yes to a date and then change their mind a week beforehand then its their fault. Like I said, this happened to us this semester.
