Perhaps the op will be along to tell us how he heard about the offer.
I've never found her profile appealing and that was before I read any of it.
If you have to cancel before her 24 hour cut off period, she still keeps the deposit! You may reschedule, but another deposit shall be required!

If you cancel with less than a days notice, She'll be after half the "arranged date fee"! Good luck with that.
As for discretion, she has pictures from her profile on tinder.
With the requirements that D-M posted, the chances of anyone, who's not happy with her service , leaving a negative review are non-existent.
