As has already been stated, it's not usually personal, unless the lady has age/weight/height/race etc
requirements that aren't met. (Check her site)
I can only imagine the frustration, not to mention the inefficiency costs of your time. Sorry to hear of your experience.
It's also a good reminder for us ladies to check 'junk/spam' boxes as I have
inadvertently missed an appt request that sat there for weeks before I noticed it. : (
Also, another thing to verify is her website, we ladies are all so different, (that's the fun right)
And some of us ladies want to be called, some texted, some prefer email, some prefer contact through pm.
And from personal experience they won't respond unless it's their preferred method of contact.
Otherwise, who knows it could be a million things, none of them about you.
If she's not available and doesn't respond...there are a bevy of beauties in Az. who will.
Have Fun
