I think you're being a bit unfair here in giving her a Negative review.
You have no proof she's a TS. Imagine if you were talking to a woman in a bar and suddenly asked her if she used to be a man. I'm guessing that woman would stare at you for a moment without responding and then just turn her back on you, so I'm not surprised by the radio silence.
Her AW profile doesn't have anal on the likes list.
This review of her (https://www.ukpunting.com/index.php?topic=324892.0) doesn't make any comment about her being a TS, although someone has commented that she was touring at one point with a TS, which is something a lot of the Brazilian girls do.
There's no sign at all of a cock and ball bulge in the video on her Vivastreet ad: External Link/Members Only.
But we aren't talking about chatting someone up in a bar though are we?
I was waiting near her postcode for her to get ready having booked her. Surely it's a valid question if you're a Brazilian girl, you must know there are lots of post-op TS countrymen about masquerading as female, one of them even gave her only feedback. I referred to that when I asked. It was a valid question, not a rude accusation.
So she has 3 options at this point:
1. She can take offence at the question and blank me, losing the booking, the cash and risk a negative review that leaves everyone questioning whether she is a post-op TS.
2. She can message to say that the question offends her and the booking is cancelled. I'd have to take that on the chin as lesson learned not to question someone's gender until faced in person with incontrovertible evidence. Would have got a neutral.
3. She could deny it and offer me proof in person before the booking starts to allay any worries. Great punt ensues, she earns, gets a positive review. Everyone's happy!
She chose option 1 and its consequences. There are plenty of negative reviews for poor comms, radio silence and timewasting on here, so fully justified on those grounds alone.
At least everyone can go in with eyes open now!
