Professor Ignoring Emails RE disagreement over grading
Your professor has probably decided that make-up quizzes are time consuming and not worth it -- students need to learn that sometimes missing an appointment has consequences etc.

I'd recommend checking if the professor is willing to drop 2 quizzes instead of just 1 for the whole class or for anyone who has a doctor's note.

That way you are working with your professor's plan rather than negating it.
