AW Central London-Rings then repeat abusive texts

First he tried to book yesterday ignoring my specific booking instructions on ad and addresses me as 'babe'. 2 flags there.
Then he didn't bother to ring me back when I replied by text.

He rings today and I'm not liking his dry, robotic attitude on phone, but agree to booking.
However by the end of the call I refuse as my gut feeling bad.

He responds with several abusive texts.
Brad, white, English, 30s, professional English accent, guarded way of talking.
