If I were in your shoes, given the apparent lack of other school options, I'd be researching homeschooling. Even if you decide not to go that route, knowing that it is a valid possibility for you will make a huge difference in this:
I don't know... We are at the mercy of that stupid teacher-- thank God she's only with her for the next 6 months, and then she'll get a different one (maybe as bad . The teacher has been in school for 7-8 years, and had no idea what the process for having a child tested for giftedness was in the school district. Therefore she never recommended anybody for it, and her point might be that my kid is not better than the 150 kids she has taught in her carreer. Which is probably accurate. And the principal (who is about 55) has told us that she has never grade skipped anybody in her carrer sooner than the middle of the second grade.
If you have other options, then you are at no one's mercy. Nor should you be. This is *your* child!
As for the "You're not my teacher" nonsense, I'd reply "I taught you to walk, to sit up, to read, to eat (or whatever you taught). I AM your teacher! What's more, I am your PARENT! I have complete responsibility for you." No reason to put up with that!
And such an attitude would not exist if you chose to homeschool anyway. After all, then you WOULD be her teacher!
