Explains thoroughly things that I don’t understand

Apr 13, 2025
I waited over an hour past my scheduled appointment time my first visit. I waited 50 minutes past my scheduled appointment time my second visit. Also, on my second visit the doctor had me watch a video on a possible new medication. He never came back. After waiting another 20 minutes the nurse came in and said the Dr had to leave. I didn’t really get to talk to him. I should get my co-pay money back. Terrible and frustrating. I’ll never return to him.
