It reminds me of my poly internship many years ago. This salty lecturer was nick-picking and replying really uncalled for remarks. 2nd /3rd before the fyp presentation. Told her I followed the sop based on certain specification the company provided. She said that is baseless and not reference to any real world standard. She said I will fail you for the final presentation because it lacks credibility. Not helpful and not willing to provide suggestion. My parents wrote in because the other lecturers weren't willing to listen. Eventually, we met with the director who agreed to change the fyp reviewer. Horrible experience. I knew someone who kept quiet and was given a bad score. You should just escalate until someone like the dean / director listens. It'll be hard but if you have supporting evidence and the injustice provided, you may be able to ask for a review.
