Intentionally Broke Key In Lock To Prevent Showings....Complain?

[Russell Brazil]

I want to ask what you agents...and maybe even investors would do in this situation. I had a showing set up, one what I suspect was going to be a very hot property.  Property was listed very late on Tuesday night. I scheduled within hours of seeing it come to market for Wednesday. I get a call from CSS saying all showings were cancelled because someone accidentally broke the key in the lock.  Listing agent says hes going to get a locksmith out there to replace the lock, should be viewable again by Fridya (after the Thanksgiving Holiday). Well today on Thursday it goes under contract.

It is now clear to me that someone likely intentionally broke the key off in the lock. So do I just let this go....or do I make an issue out of this.  I of course am incredibly upset, and I expect my client to be very upset.  So what would you all do?
