Been on this site for while but not posted, thought was bout time I contributed.
Joined in 2015, first post 2019 - yup, that would count as a "while". But you've started contributing, which is good.
Less good is the considerable amount of important information missing from your post:
Comms were great up to meet date, then decided to mess me around with random mesgs and excuses, then cancelled on me last minute after hotel was booked and i was waiting in room.
Where was this? Ideally, you'd put a town or village in the subject line: "South East" is quite a large area. (Although I'm prepared to believe that there really is a place called "Timewaster". Probably in Kent.) Since this was clearly an outcall - something worth mentioning explicitly in a review, btw - you must know where it was.
Another thing you didn't explicitly state is that you and the girl agreed a time and date for the meet. Your wording is slightly short of that: "Comms were great up to meet date, then ..." Did you agree a time and date, or not? If you didn't, then what you've written isn't even a review, I'm afraid, per site rules.
Being mucked around is infuriating and if she was the one doing the mucking then you have every right to post a negative review on here; but are you sure the mucker was her, in this case?
On a different aspect of the (possibly) punt, at the time of writing, her AW profile page quotes her outcall rate as being TWO HUNDRED AND FORTY POUNDS FOR ONE HOUR

. How long was your booking?
