I recently set up a meeting that got cancelled at the last minute.  I'm not sure why she cancelled since I did everything the way she requested.  I tried contacting the provider, by sending several emails (which was the way we were communicating), but never got a response back.
Is this normal?  Do most providers, after cancelling, just don't respond back?  Do they consider a second meeting?

See this recent thread:  
"Provider changed her donation after agreeing to date.  Posted 10/18/2013 at 4:05:35 PM"

Sure it had nothing to do with you. Or she would not have booked it in the 1st place. Give her some space and email in a few days.  

will probably happen.

Sometimes, shit happens; really bad shit.  Yes, you could wait to hear what the excuse for not contacting you or replying to your emails within a day or two is.  Car accident - hospitalized on pain killers for 5 days ... stuff like that can explain the lack of reply.  "My grandmother died -- again -- and I had to leave town in a hurry." may explain the cancellation but not the reason why she couldn't find 2 minutes to text or VM you an apology within a day or so.  

Want to see her again give her some space and try again. If you want to hold a grudge then move on.  

See what reviews say. If she does not have any pattern of this and you really want to see her, like Sindee said try again in a week and see what response if any you receive. Life happens unfortunately and some circumstances are unforeseen. The only time I had to cancel was on very short notice and I actually dropped off the donation but couldn't stay. She offset our makeup session which was greatly appreciated. Bottom line IMO is you should send her an email in a few days expressing your concern for her well being and hope she is OK. Ask her to contact you when she is available (in a no pressure way). If you get a response - hear it out and trust your judgement. If no response, time to move on.  
Good luck!

Her reviews show no pattern of this.  In fact it's the entire opposite; she seems very professional.  I'll follow your advice since I donwant to see her.  The only thing I don't quite understand is that when she cancelled, thirugh an email, she suggested to meet the next day.  So I sent her a reply but got no response anyway. Thanks anyway for your advice.
