Try to call back and leave a clear message, say your phone number slow so they can understand it. Many times people leave their number on my machine and I have no idea what the number is. Also if you have the address to your therapist you might just want to stop by and talk to the office help. I am sure there will be some paperwork to fill out so maybe you can do that and have it done before you go in. Good luck - hugs for your day.
