Recently got an email about cancelling my admission at UC Berkeley

all other classes on my conditions of admissions are either major prep or IGETC required classes. I spoke with admissions today. They say although it is not a major class it was reported on my application and therefore must be satisfied by the deadline. I am just planning to work on the appeal now.

Yeah over email only she was not in the office today. I asked her if she would be able to change the grade and she says that I earned a D based on my work that semester and there is no way she could give me extra points to get a C. She said she would support me in submitting another request for an EW as a reflection of my situation. Do you have any advice on how I should respond?
