Yes, I'm quite aware that guys complain girls are often difficult to contact. Personally I have my phone with me from 8 or 9am in the morning until 8pm at night. I check emails at least once a day, and in between appointments when I'm at home.
I've had one or two complain they've called a few times on a particular day, say they couldn't get me - when I ask it's because I've either been in an appointment or on another call. I do leave a voicemail advising when I will be free if I am in a booking but some have said they don't bother to listen to messages.
Most of us try our best and unfortunately guys don't always realise we could be otherwise engaged - expecially the more popular ladies. I do return calls but ONLY if specifically requested since most guys do not want random replies at all hours from escorts! I have also replied to texts - but sometimes I've been in a long booking and it's late at night - which makes it difficult to decide whether it's now convenient or discrete to reply.
On the odd time I have, many hours after the event I've sometimes gotten a "who's this!" text back. No way I'm continuing that conversation.
