I've been plagiarized

I've never been so filled with rage. My partner tried to present my work as our group work and when I confronted her, she claimed to have lost the version with all of her work. She also failed to turn the paper in which she was supposed to do last Thursday, and which I couldn't do because she never sent me any of her work due to "technical problems". To top it all off, the teacher doesn't want to hear about my "personal problems" and wants us to finish the paper by tomorrow which makes it 9 days late.
