Thank you! I'll email my referee explaining what happened(Original post by PQ)
You can talk to your referee and ask them - if they aren't willing to put that information in then fine - although your results slip should show that you didn't attend the exam so you should have some proof - your grade on your results slip should have a # mark next to it (# indicates that you were absent for part of the exam in the subject and awarded a zero mark for this part.).
What are your thoughts?
