Darnit I lost my post.
Ok, reconstruction time.
1. Go to the professor, have her write down what happened, the problems with the interpreter and sign it. Ask her if she will assist you with your formal complaint.
2. Make a formal grievance in writing with the disability services department https://www.ohio.edu/uc/sas/ You should be able to not have this woman as your interpreter, but she's also gone far far beyond that and that all needs to be written down.
3. Contact the Ombudsperson. This is someone who is neutral and helps you solve problems that you have with the university. They do research and they can mediate it if you like but you don't have to mediate it if you do not want to. https://www.ohio.edu/ombuds/
4. Contact the Office of Equity and Civil Rights Compliance https://www.ohio.edu/equity-civil-rights/index.cfm because she and the office are denying you your civil rights and equal treatment. On that page there's a link to Diversity and Inclusion, and you can file a report on the incidents where the interpreter was biased. However, I would go to the Equity office first, talk to them, and see if a report through them is more appropriate than making one through the Diversity and Inclusion office.
5. Contact the Dean of Students They ere there to support and aid students. https://www.ohio.edu/deanofstudents/index_old.cfm Contact the Dean, associate Dean and assistants and do it in writing. They are all listed here https://www.ohio.edu/deanofstudents/about.cfm Additionally, contact the Dean of your college. English Lit major? Contact the Dean of the College of Arts and Sciences. Contact the Dean of the English Department. Both are important, both care for how their departments are run and they care about having their students' needs met.
I think I got them all! You have good options and places to make the disabilities office do the job it needs to do.
