Looks like their profile's been taken down, I did a quick search with their email and only found your post, a bad review, and a model page that no longer exists. 
Eros requires you to send in an ID and a verification photo of you holding the ID, but this doesn't mean the person is legitimate, it just means they're the same person from the photos and over 18.
Great advice from Mistress Tissa on checking out who you're sending to and not cutting corners to save a buck!
