They have either accepted the circumstances and decided that their award is appropriate or they have rejected the circumstances and awarded based on your results
If it is the former then nothing is going to change your award ... if it is the latter then more evidence may help to convince them of the seriousness ... tbh though I am not really sure what this evidence actually adds
As has been said you need to talk again to your Director of Studies
Have you talked to people in the Student Union to see if they can support you in this situation
