ST...you read it incorrectly. He told her 15 min BEFORE HIS TIME WAS SET TO BE OVER that he wasn't coming. 2 hours and 45 minutes into his "window."
Loser.
What can you do about getting decent notice about when/if he is going to show up? The day before doesn't seem like you are asking too much. Is it a matter of contacting the lawyer and maybe just copying the ex on the communication (after trying one last time that you need decent notice so you can plan your life)?
