I had the chance to engage a low volume provider who had great reviews for when I travel to the city.  I live far enough away that I only get the opportunity to hobby a few times a year.   I set up a date with the provider 2 months ago, and we have written back and forth several times since.   I noticed she had stopped touring two weeks ago, so I wrote her to confirm our visit.
My e-mails were returned undeliverable.   I tried to call, but her phone mail was not set up.  She did not respond to a text message.   Her last TER review was back in July.
What should I do?  I don't want to stand up the provider, but I don't know how to reach her.  I would still love to see her.  I don't want to lose one of my few opportunities to hobby.  I have been stood up once by another provider with top reviews.   I don't want to put someone in that situation.  Please help!

If she doesn't return your correspondence how can you be standing her up?  In the hobby, anything booked 2 months out is always going to be subject to change.  You have done your part.  She may be on a break or retired.  If she wants your money she will get in touch.  I would suggest moving on.

She is the one who has cut off communications. There is no way you can be accused of standing her up.

Although there's no telling what could explain her disappearance, you have to assume that it is by her choice and proceed on that basis. If she wants to get get back in touch, she'll find a way. In the meantime, you should line up a different provider so that your hobbying opportunity doesn't go to waste.

If she is well reviewed, you could try a PM here.  If she has a web site, you could try contacting her through it.   You can watch her profile or advertizing sites to see if new contact information surfaces.

Typically a scheduled appointment is not "on" until confirmed within 24 hours of the date.  The fact that her email has changed suddenly could mean she was hacked or the account cut off by the servoce provider.  (I had this happen with a Favorite lady...  I finally called her & found she had a email problem.  She gave me her new contact information.

In the meantime, she has dropped out of sight for what ever reason.   It's getting close.  I think you need to get "advance screened" with another provider...   so you do not lose the opportunity.

I had a well reviewed provider NCNS me not long ago & I lost a rare opportunity to play.

She was either: 1) found out by family; 2) caught by LE; or 3) stalker client.

If she has disconnected all forms of contact, then you cannot be considered NCNS (can't be NC if there is no way to C).

Make plans with another lady. Hopefully Lady 1 gets in contact with you before the date. If so, then you can cancel with the new lady. If not, then you have not wasted a trip.

"I hope all's well. Sorry it won't work ou for us, best wishes for your future."

Immediately start looking for the lady who will return your correspondence.
