Do you keep records of those who didn't reply to you? Is hard to remember someone who didn't reply and think "oh, I remember him, I texted him and he didn't reply".
Maybe the escort is with a client for an overnight and simply can't reach his phone at the moment, he's flying somewhere else next morning. No excuse for me for someone NOT to say "sorry, yesterday I was busy" but the way you phrase it (in your own particular way) sounds like a thread, like you (and I guess others) would take a no response as personal insult impossible to be forgotten.
