It's just the nature of the business. My most recent one went something like this:
Me: text "Are you available today?"
Her: text "Getting my nails done this morning but nothing after that."
Me: text "Great. Will 1:30 work for you?"
Her: text "Sounds great, See you then."
Me: text at 1:25 - "I'm here, room #?".
Her: no reply
Me: phone call 1:45: "Are we going to meet?"
Her: phone call 1:45: "I thought you were going to call first. I am still 15 minutes away."
Me: WTF?
Me: text 2:00 "I have to go back to work if you aren't here really quick."
Her: text "I am getting a speeding ticket"
Me: text "We will have to reschedule."
Her: text "Uuuuuggghhhhuuuu"
The crap you put up with in the hobby.
