Is this a review?
Did you make a booking, pay a deposit and then she cancelled?
Or did you ask for a booking, she asked for a deposit and no booking was made?
Not sure I really understand the relevance of the postcodes?
These can be shared days after making the booking, a few hours prior to the meet.
I think it is good to be vigilant, maybe post a warning, since I wouldn’t be surprised if deposit scamming becomes the only way for some to get money during the lockdown, but you can’t be certain in this case.
