In no particular order:
-FYI, your sentences are long and rambling, and hard to understand. That's not a good way to go when you are trying to communicate a point. As a result, I'm not clear as to the exact steps that were followed to create your appointment.
-Playing by the rules = following her rules. There is NO blanket rule of conduct, or "rules of professional conduct" that cover this hobby. You are paying for sex, an illegal endeavor, and the women that you will see do not attend "hooker college" to teach them how to behave. You may think that you have the "right" to expect them to behave by a certain set of rules, but you will often be disappointed. For the best possible experience, get completely tuned in to HER rules.
-You cannot review a "no show" on TER, so there will be no review of this experience. If you truly feel that it was 100% her fault that she flaked on you, the best you can do is post about it on your regional board.
-If she "made no effort to reconfirm your appointment", then there WAS no appointment. Sending her an e-mail as you went out the door is NOT confirming an appointment; how do you know she even read it?
-If you suspect that she wouldn't open the door because she looked out the peephole and saw that you were a black man, then you may be right. Some providers will not see black men, as has been discussed here and on the general board many times. It's bullshit, but there is nothing you can do about it. Most providers who feel that way will at least put it in their ad, but most black men who want to avoid this hassle will mention it early in the booking process, just in case.
-Last, but definitely not least, what I glean from your post is that this is a back page provider who has no reviews, who you are visiting at her home. Correct me if I'm wrong. That is the least possible professional scenario that you can find in this business, and it is completely and entirely your fault. You have a TER membership, this is why TER exists. Do some homework, read reviews, see reputable providers at decent hotels, and you will not have experiences like this.
I'm sorry to be so negative, but the point I'm trying to make is that as a hobbyist, you can go around "expecting" other people to behave a certain way, or you can take the responsibility to do things the right way, be thorough in your approach, and get the most out of each experience.
