I tried to cancel my appointment, but...

My primary care physician referred me to the sports medicine department at the Sunset Medical Center in Los Angeles to look at my shoulder. I scheduled an appointment in lieu of my shoulder getting better which, thankfully, it has. So, I tried to cancel my appointment, but was unable to do so despite following the instructions on the appointment card. I called the appointment line (as it said to do) and spoke to someone who told me he couldn't do it, that I had to call the sports medicine directly. When I called the department directly, no one answered and there was no way to leave a message. So, I then went online to cancel the appointment via the appointment center at Kp.org. Unfortunately, it too informed me that it was unable to process the cancellation. So, after three failed attempts to do the right thing and cancel my appointment a head of time, I simply gave up and just didn't go. Admittedly, I hated being a no-show. (I never like to stand up a date, of course.) But, that like the rule says, three strikes you're out.
