Really? They were too busy to respond, and you think that is a bad thing? Especially when they are offering special services that you were obviously not the only one interested in?
Not sure what your original text was, but sending a message "?" is kind of rude, maybe if you had said "Hi, I had texted a while ago, I understand you are probably very busy, but was wondering if I would be able to get in today?" you might have gotten a less terse response.
They normally have ads up, but the total lack of ads right now suggests you may not have been the only one they were unable to accommodate, and that their dance card is sufficiently filled. Not sure when they took down their ads, it might even have been between your first inquiry and your "?"
These ladies are well reviewed and well liked, and I'm pretty sure they won't miss your business. I would not blame them is they refused booking you in the future after this uncalled for post. Your loss, really.
