I am a disable adult taking online classes with Walden. I feel I am being discriminated against. First, I had to go above my professor's head in order to complaint. For almost 3 weeks, I tried to get in contact with her via phone about my disability, services, and questions about one of assignments. She told my advisor that I was being disrespectful to her so they gave me a verbal warning due to code of conduct. The director of problem review emails and found that the advisor was out of line and there was not no misconduct nor was I being disrespected.
Also, I receive extended services through disability services through the school. During week 3 and part of week 4 I was not get my work turn in due to being sick and to things out of my control which was related to school activities. I communicated with professor and she first agreed to work with me. Well she changed her mind and disregarded my disability services and gave me zero. then she changed it to 12 out of 30 which was still an insult to injury. I then got a email from disability services stating that they couldn't help me and basicly felt I couldn't do the work cause of my health issues and they would help me withdraw from school. I feel as if I am being forced to withdraw. I witness them do this to another disable student while attending residency in atlanta ga. They forced him to withdraw cause of his medication was making him sleepy. I have witness names and numbers who know about this gentleman. Also, I have all the documentation (emails) written between myself, professor, disability, and program manager. SInce they receive federal money from government they are required to provide accommodations to students with disabilities. Can someone help me please?
