Has anyone had any luck with a well-stacked provider going by the name of darla?

She looks fine on paper and we chatted like good friends over the phone.  She promised to come over to my place last Saturday, but she stood me up.  No word, no apology.

To add another twist to the mystery, the girl has another ad in New York, but going by a different name.

Do we have any Sherlocks out there that could explain this mystery to me?
