Sorry this didn't work out for you. Obviouosly the two of you didn't have a meeting of the minds. She should have made it clear when to call to confirm.
I am very specific, especially with newbies, on when they are to call to confirm to date and get directions.

I e-mailed several days in advance...she responded next day to accept.  Next day, we talked on the phone for a few minutes to get a feel for each other.  Next day, she called and we set up a time to meet later that day.  Everything went off thereafter without a hitch, and I left that evening as happy a camper as possible.  We exchanged follow-up e-mails, and have met dozens of times since over past six years...and will be twice next week.

Make sure to keep in touch during the 24 hr. window before your appointment until you are established with her.

You probably spooked her. Don't worry too much. Take this as a lesson learned. My advice is to make sure you have a TER vip membership and find a lady who prefers to be called as the initial contact. This way she will see that your number is not blocked and she can check the number out. Know in advance what her rates are and don't talk about them on the phone. She will probably give you instructions on what time to call the day of the session.

I always use the phone as my first contact. Gives us both a chance to break the ice. After we agree on a time and date I always tell her that I'll give her a courtesy call an hour or so before the date to let her know everything is a go on my end. During that call, I will get final instructions to her incall OR she will tell me to call when I'm at a certain landmark.

First contacts can be tricky. Play by her rules. Know what NOT to say on the phone or email. Be polite and you should do just fine. Good luck. We all have to be safe.
