Office review - disappointed, you miss an appointment you're done!

I have an S shaped septum, collapsed nostril flap at which I do not get air in my right nostril, my nose is crooked due to taking a ball to the face and a clogged duct in my cheek that needs to be surgically removed and biopsied. In addition, a mass in my right sinus cavity that showed up in my dental CT scan that has concerned me as I already have breast cancer. I had the appt in my calendar, took off work, drove 45 min and was at the clinic, however was advised my appt. was the day before. I never miss appts and was upset at myself for putting the day in my calendar as the 19th vs 18th and missed the appt. as I had waited 2 months to see him. His office advised I could not rebook as his policy is you miss an appt. you're done! We all make mistakes even Dr. Shadfar. For a Dr. to dismiss a patient after waiting 2 months to see him is very arrogant and reflects his lack of empathy and compassion for patients that are suffering due to a medical condition.
