Is there an option for zero stars?

Is there an option for zero stars?
I had scheduled an appointment for my son a month and a half ago. When we showed up at the hospital in Bellevue today, I was told that they rescheduled us for November 3rd because the provider we had scheduled with originally does not see cases with my son's diagnosis. So I asked why no one had called to tell me about this, and they said someone called two days ago and left a voice mail message. I checked my cell phone call record and there's no incoming calls from the hospital. There's no voice mail on my cell phone. So they said maybe they called my home phone. I checked the call log on my home phone, and no calls or voice mail from the hospital either. Obviously they dropped the ball and they have no excuse. And now we have to wait more than a month for the next available appointment. First of all, how did they even schedule me with the wrong provider to begin with? It's not as if I requested a certain provider, and I made the mistake. They scheduled me to see a certain provider and then supposedly called me two days prior to the appointment to notify me of the mistake and to reschedule. I had to take time off of work, and I had to take all three of my children out of school early so we could make that appointment. That is crap.
