Wow, I think it stinks that you can't at least leave a message.

My own therapist's voicemail says to leave a message of any length and he'll get back to you soon. The times I've called he's always called back by the next day (except when he was out of town). At least once he encouraged me to call him (I was dealing with a particularly bad crisis), and he has never been anything other than very supportive by phone. He's called me back on a Saturday and on a Sunday before when he couldn't call during the week (I've left him a message late in the evening on Friday before).

He has called from his cellphone before and had me use that number; however, if I'm calling him I always call the office number so he can check his messages when it's convenient. He's never given me his email address and I've never asked for it.

I think at minimum everyone needs some way to leave a message even if their therapist's policy is not to return calls. How else would you let them know you needed to reschedule?!

P.S. Apologies that this post doesn't offer any suggestions. I don't know what you can do other than talk to him about this issue and explain why you couldn't be at session.
