Was she asking for gift cards or cashapp for a deposit?  That’s a scam going on now.  NEVER pay in advance.  This is a cash in hand business at least until you know each other pretty damned well.

Sounds like you've given her plenty of time to respond.  Assuming you're not a creep (which is sounds you aren't) the NCNS was not justified.  Providers are always going on and on about how valuable their time is, requiring deposits and blackslists for noncompliance.  I can promise you that my hourly time is more costly as it relates to my income than any provider I have ever seen.  I'd post it - with it the caveat, "I welcome (so and so) to respond or contact me with an explanation and I'd gladly delete this post or add to it that the situation has been explained and rectified." just my two cents.  

I'd wait a short time for things to cool down, then try to make another appointment with her.  If she follows through, chalk it up to her having a bad day.  If she doesn't respond, you know it's time to move on without the need of knowing why.

Got ghosted women tend to do it with no explanation. U probably  did something  to creep her out during ur last session and she probably  didnt remembered till she seen ur face when u pulled  up. My advice  move on and patronize some one who appreciates ur buisness

This sounds sexist however it can apply to men or women, in this case it is a woman

women are like Marta buses, stand at the stop long enough another one will come by to your liking.

If she ghosted you and you are out nothing but time then move on and look for the next bus

If you had seen her many times previously why has she not reached out to you? She does not appreciate your business, nor does she respect your time. She could have a pimp. She may have double booked. Who knows...

The fact is she doesn't care. You stated she was on p411 logged on attempting to catch another date. lol It's funny when I read the comments this is a cash hand business, don't send money, it's a scam. BS. Find you a me. Someone who respects you & your time.  

Move on. She obviously did. You get what you get when dealing with non-professional providers. This is a business, and not just a cash business. Professional providers accept all forms of money because were smart. Cashapp, Venmo, Paypal, Zelle, Crypto Currency, and so many other fun options.

Makes no sense unless....
A life changing event happened at that exact moment such as
Hubby decided to come home early or she was trippin on some acid or
whatever people trip with.  otherwise she owes you an apology and a free make
up session.

Give her a week initiate contact and if she won't pick up name her.

Time to move on !!!  Perhaps there is someone you've seen in the past that you could connect with !!  

It is what it is....more important to you that to her !!
