I arranged an hour meeting towards the end of last year, it was about a 40 minute drive from where I was, about 10 minutes away my punting phone bings, "sorry, double booked, I can only do 30 minutes" which was a right pisser, then when I arrived and I text to ask for the actual location she replied saying she was going to have to cancel.
Really unprofessional, I won't be bothering again.
