Oh crap, wasn't expecting that. It does sound very suss that they have kicked her out and then tried to dump the responsibility of the school fees on you around the same time. Um.. hello.. just because you kicked her out because she's "rude" doesn't mean that you don't have to take responsibility for your decisions and finances.
I hope that it all works out for you. Although it seems like the end of the world for you DD she will be fine if she has to move schools.
