Does the infusion scheduler ever answer the phone or returns messages? Very frustrating and disappointing.

Yes, I have had to reschedule appointments and she will call you back. I've been at her desk while she did it and there was someone else waiting to reschedule, too. It can be frustrating especially when you're not feeling well. However, once you get to your appointment, the staff and environment make you as comfortable as possible.

You can only leave messages during business hours for some reason. When you call press option 2. Follow the instructions to talk to the department directly. But make sure it's during business hours. If not, the call just disconnects.
