I would have contacted Ad Staff with my concerns rather than submitting a report without any real proof. Maybe when they read this they will request a new verification picture?.
In the mean time you are within the rules to submit a review as you met the lady but didn't go ahead with services, if you select that choice not only can you write down your grievance but you also get the drop down options on accuracy of pictures etc which will warn future clients that may not get to see this thread or even remember it in a few weeks..
