It's better if you e-mailed her yourself. When you e-mail, all you need to ask is if she is available to see you on a date and time that you want.
If you are looking to book her in advance, then e-mail and give 24 hours for a response. If no response, then I would conclude that she is indeed a fake, and move on to the next escort.
If you are looking to see her on the same day, then if she has a phone number, call her or text her to ask availability. If you call and there is no response, then send a text. Give it 1 hour for a response. If there is no response, then move on, and conclude that her profile is indeed a fake.
If you are interested in seeing that WG, then it is YOU who needs to make the contact, not others.
