Interesting! I just had an email suggesting that the phone call yesterday may have been misinterpreted and asking if its convenient for me to be available for a conference call with the Practice Manager and other relevant parties at 12 today.
Now what????
Wow!
Can I suggest that you have all the docs about Dr Unwin, and links to the educational module for medical professionals (put together by Dr Unwin) ready to hand, so that you can refer to them, if necessary, and send them over by email, following the conversation.
Stand your ground.

I will be rooting for you!
