Foiled doctor appointment

Well, I had a doctor's apointment today, and I was going to a new doctor that I had chosen from my insurance plan's website. Well, I go to the place the website told me to go, and lo and behold, I couldn't find this guy's office anywhere. So, I ask one of the nurses in the place where it should have been, and she told me to try another place. Okay, I'm doing fine, and I go to that place, but I called my mom and asked her to call them to tell them that I was going to be a bit late (my mom was the one with the phone number). I go to the place, only to discover that the person who I thought I had the appointment with had retired. I go to my car, fighting back tears 'cause I was so frustrated with the whole shenanigan, when I call my mom and discover that the place I needed to go was across the street, with a completely different doctor. I'm a wreck at this point, and Mom ends up telling them that I'm hopelessly lost and I'll have to reschedule. We don't even know if this person is covered by our insurance. And that, ladies and gentlemen, is what happens when I try to make my own doctor's appointments with a new doctor.
