I fired my ophthalmologist today

A week ago I called my ophthalmologist's office to speak with her. I was told she would be out of the office till today. The lady on the phone asked me why I needed to speak with her; I explained that I wanted to buy a tonometer, and that if she was not in the office to have one of the other ophthalmologists call me. I didn't hear back from her the rest of the week; I was simply ignored.
