I would be beside myself... but when I had kids here I would tell them no if the parents couldn't... I hate when parents put you in the position where you feel you have to take charge!
I would let them know how you felt but I would call... The thing is, if you react in anger you may not be heard... these people need a wake up call but if you do it to vent, they may not hear you. If you can calm down, and speak to the mom in a way that will be more of teaching you may be able to show her how you feel... Show her how it feels to be on the other end of this. THey got a nice night out and you got nothing but cleaning and stress....
If you can open their eyes so they see the monsters they are throwing at the world maybe they will think twice before they allow the kids to trash the next house!!! I agree that you shouldn't allow them back though.
