When my appointment time was approaching, I was very sick and left a message on a Thursday evening to cancel an appointment for the coming Monday I received a bill for the missed appointment. At this point I should have been done with these guys but shame on me, I later re-scheduled the appointment

I show up on the new appointed time, only to be informed that my appointment was canceled due to neglecting to confirm the appointment. To my surprise I asked how this could be as I received no calls, emails etc. The girl at the desk was completly dismissive and said she made the calls herself. In her haste to prove me wrong it was learned that she called a wrong number. No apology or any sense of blame and simply said I could reschedule. She said it was policy that if the appointment is not confirmed, it gets cancelled. The irony here is that my previous appointment was not only NOT confirmed (I actually left a message that I was not coming) they still sent me bill for the "no-show"
