I've had this before with PDC Chloe 2395. Seen her twice then never responded for some time. Then I caught her on a good day, booking was easy after that.
Popular girls book up quick then stop replying or looking at msgs It also helps to give a detailed response I found. If they get 20 texts saying when are you available next for HH? vs. one long text describing details, length of encounter, your info, what times you are open for (anytime past 630pm?). You will probably get a response quicker.
