She did a similar thing to me. We had tried a couple of times to fix a time over a week or so, but no joy.
On the particular day I text and asked for a mid afternoon appointment, no response. around 4:30PM I get a text - "I'm free now". I respond straight away can we do 5PM for 30 minutes. OK she says.
I arrive at 4:55 and park in Cephas St, pay for parking until the restrictions end at 5:30PM and text her to say I'm outside - no response.
I call her, she texts back, "I'm in the shower, 5 minutes".
10 minutes later I text and tell her I'm leaving - no response, so I leave.
5:30PM, she texts me and says she's ready.
I tell her I've left already.
I did finally punt her a week or so ago; I'm going to do a review. It's Positive, but she's not my type.
