She has been bad at comms for a long time, not just recently. Often has the Available Today light on and doesn't respond to emails. This thread has been good in that it has highlighted that several people have experienced the same. Most of us just moved on, but actually should have posted about it in order to highlight the issue which is what the forum is for after all. No change in the world ever happened from people who just sit back and take it.
In contrast, people who have seen her a few times previously seem to have ok comms with her which bears out what i said earlier.
Someone like Devilish Diva (who have never managed to see either) always at least says if she is not seeing non-regulars and takes her profile down as soon as she is booked up or not working, which seems a much more sensible system if you are over popular, ill or don't work often then you won't get overloaded with emails.
