I recently tried to connect with a provider. I sent a text, one of the contact options, gave as much info about myself as I thought would break the ice and commented on a possible reason for her not wanting to meet, age difference but wanted to meet her regardless.
 Now all I ask is for the provider I contacted to respond. I get, busy, and all the other reasons, but It takes seconds to respond to a text. There is a lot more that goes with this story but for me it was the key reason for what turned out to be a long story. And truthfully it’s just more bitchin’ and moan'in,

END OF MESSAGE

There are too many unknowns here. How long has it been since you contacted her? What specifically did you say in your initial text? Was it something that turned her off? Did you leave out the info she needs? Is she active now or on hiatus maybe?  
.
There may be legitimate reasons she hasn't gotten back to you, and of course there are times when the provider might be unprofessional in her response time, but like I said, there are just too many unknowns here to come to to a conclusion of who is at fault, if anyone.

Why make a comment to her about her not wanting to see you because of your age difference? It doesn’t break the ice it makes you look like you lack confidence to put it mildly. I’m sure there is way more your leaving out.

Every provider is different. Did you read her website before contacting her? I myself personally, do not appreciate anyone reaching out who does not include the contact information I require from my personal website to consider anyone for a possible date.

This one is real easy, just two points.

1) I mean, don't do that. It is a turn off. You told her she might not want to meet you. She believed you. If the the issue was serious enough for you to mention, it was serious enough for her to consider.  
.
2) No response is a response. If a provider doesn't respond it is clear she is not available to see you. You are welcome to try again at a later time but she sent a pretty clear message. Clients, like many customers, tend to be entitled. Here's the deal, just because a provider puts an ad up and fucks for money doesn't mean she is required to fuck you for your money.  
.
Honestly guys need to be able to handle rejection. You say there is a lot more going on with this story and that it is a long story. I doubt it, seems like a simple story. You tried to book a provider and she wasn't interested.

It’s already been asked above. Did you read her website? Did she ask for screening info? It seems from your “short story” version that you did not provide the requested info.  But from your entitled perspective, she’s required to engage in an extended dialogue back and forth on whether you two are a good fit.

Another scenario you didn’t address. You were in contact with her assistant and contacted him/her during non-business hours.

Another scenario you didn’t address. You reached out to her and didn’t request a time for a meeting. You left it open ended. So she replied when she got back from her extended date with another monger.  Maybe if you had said “I would like to meet you the day after tomorrow”, she would have quickly responded that she won’t be available until she returns next week.

So you sent her a bunch of what you thought was importamt info about yourself to determine compatibility for a date.  She was looking for you to request an appointment (date/time/duration). End of long story.

What does his age have to do with her seeing him or not, unless there is MORE to his story than what he is telling.  Is he in such poor physical condition that he may go into cardiac arrest during the session, in which case she would have to deal with the embarrassment of summoning the paramedics for a customer she just met, and that may be an automatic pass for her.  

 
When describing themselves in the initial contact, older guys should be able to say, they are an older gentleman, fit and in good health, kind and generous.   Saying something negative like, "I will understand if you don't want to see me because of my age," brings a dark cloud over the session before you even meet, so not surprised she blew him off.  

 
One of the guys I most admired years ago was an octogenarian in San Diego who went by the handle of "rockynutz."   Always entertaining, and reviews are still up.   He retired from this hobby a few years ago.  

You are a classic time waster.

Of one of those Progressive Insurance Commercials. Don't be like your parents...lol
From where I sit, You said more then what you should've said on your initial text. Like that age thing, I dunno know why you'd bring that up...but you did.
Sometimes you have to know or gauge your recipient and how to reach out to them.
Less is more????
