Its obvious that she was afraid I would not turn up and made another back up appointment 30min after mine.
As some of these WGs get a number of no-shows, this is what they do.
Many of them don't ask you clearly to confirm nearer the time, but it's what I am going to do now after one escort, Mariann in Harrow, cancelled my booking a couple of weeks ago because I missed her texts while I was driving.
Like you, I only booked about 2hrs in advance so one would have thought that was close enough not to confirm later, but there you go.
Thanks for the review - apart from her double-booking you, the experience doesn't sound great even when you get there.
