I sent an email apologizing that I'd need to cancel the session and asked what I could've done better, never heard back. As far as the discussion on the definition of "well known" this is someone that every single person in the BDSM community, at least in the US, would recognize I just don't want to name them. I think I was communicating with an assistant for most if not all communication. Which I don't have an issue with, it was just odd that I got no response. This communication was wildly different than other dommes I've seen before where once we agree on a date I'm instructed to send the deposit and then once it's received I'm notified session is confirmed. And then typically I'm instructed to confirm the day prior as well. And when I do I always get a response back so I know everything is still good
