I really enjoy getting to know providers, DURING OUR SESSIONS. If a provider is willing to text/email leading up to the appointment and flirt, that usually lead to even more fun sessions, but I don't expect it.
I also don't expect them to continue texting/emailing after our meeting. I'm not saying the OP expected this, or pushed his luck, but judging by his reviews, it seems maybe something didn't go to his liking 100% and he took it out on the provider, instead of owning it.
As hobbyists, complaints like these leave a bad taste in provider's mouths (no pun intended). It's incumbent upon us to emember they have a life as well, and whatever reason they cancelled for (personal or otherwise) needs to be respected, as there may be valid reasons for it.
Lastly, and this is not intended as a direct criticism of the OP, only being able to judge by his reviews and a complaint about a lack of communication, I would venture to say maybe his expectations are misplaced.
They aren't here to text/reply to our whims as long as we want - all we should do in these instances is send a polite email to the provider expressing our disappointment in not being able to meet them, that we hope everything is okay, that we hope to be able to meet in the future and that we look forward to hearing from them. This is true in every aspect of life.
