It's not unknown for phone messages to get garbled/lost/forgotten - I'd definitely try calling them back a few more times - make sure that you leave your phone number on the message, just in case they're trying to call back a wrong number. If that doesn't work, then perhaps ask your GP if he can contact them again for you.

It sounds like it might be helpful if your partner could maybe attend some of the counseling sessions with you? It may help his understanding of your perspective (and you of his).

Let us know how things go.
