Contacted provider who had great reviews.  Problem was she only dealt n texts.  Gave me an address with apt number.  Asked her to call me and verify but she wouldn't.  Didn't know if I was walking into Leo or a mugging. So I left.  Is this type of communication commen?

Apparently, she had made it clear, she only texted, not talked on the phone.  Many providers are just the opposite, talk but no texts.  It's always a good idea to follow the provider's rules, regardless of what you want to do.  She gave you the info you needed, so why was it necessary for her to tell you the same thing verbally?  Just because she texted you the information you needed does not mean she is LE or you're being set up.  That's what she is seemingly more comfortable with.

would have gained by hearing her voice?  Personally, I'd rather get the location as a text. At my age, I wouldn't have to worry about forgetting (or mis-hearing).

I personally agree with you- no matter how many references a client has, I don't meet with ANYONE until I can talk to them for a few minutes on the phone. Subtle things like tone, affect, breathing patterns, word choice etc are INVALUABLE when it comes to judging things like character, compatibility- and to touch on a topic that was recently covered on the General Board- SOBRIETY!  What good do 10 P411 "OKs" do if the person is slurring their speach and unable to perform sexually because they are falling-down drunk?

That's really for one simple reason: I just hate talking on the phone. Always have.  

I never really understood that, but I guess it works for some. If she has good reviews and a lot of them, I doubt it's LE. She could have a pimp or booker though.

e-mail only until the appointed time. I then call upon arrival to get room or apartment number.
This is how the ladies wanted it.

Mainly because email is easier for me to deal with. I have a civilian job, and I can have my Jenn email on my civvie phone, whereas I use a separate phone for texts/voice. The only time I hop on my phone by voice is if I'm having a hard time finding my client, or they can't find me. I only text on the day of appointments, for the same reasons. Otherwise it's email all the way.  

And a provider who categorically refuses to have a two minute phone conversation, even after the client specifically requests said brief phone call! The later is what the OP found suspect.

I hate talking on the phone too. I prefer to book appointments thru email so there's no miscommunication.
