Had a similar if not as abusive dealing with her.
I was due to confirm a booking on the day we agreed. I got a message from her at 1130 on the day asking why I had not confirmed. I told her was going to do so but this was not good enough. She called me a waste of time and said she wouldn’t see me. She didn’t put it so polite mind you.
Our meet was agreed for later that day so plenty of time to confirm.
She is now on my blacklist and will stay there.
