Appeals process and no rewrite option for Capestone Project

I'm a 3rt Year student. All modules for the 3years were passed. The Capstone project i failed with 7 marks and reading the comments the Subject advisor made I'm sure he failed me just because he did not like a Question I posted on the "ask the tutor" function on student portal earlier in the semester. I'm not sure what i got wrong as there is no clear break down of how marks were allocated. Now I have to redo a whole semester because of a lousy 7 marks. This is messing with my future. There is no way to resubmit the project. It feels like this is a money making. So sad that in the 3 or 4 classes I was more confused . 7 marks. Is there a appeals process for The Capstone project also? Why is there no rewrite/resubmit options for this.. Maybe my subject matter was ****py. I wonder how many lost out on completion of their degree because of 7 or less marks.. Sad Sad Sad
