hurry up to register for another test, just show the evidence that you are registered and attemt to improve your score.
then use express courier to deliver your package. please note that your date may be delivery, not dispatch! if you do not register within days, include in your cover letter a paragraph that you are registering for another test session. I hope you spent more time preparing for the exam this time.
I know from my own experience that the exam result partly depends on technique, I am sure you considered this point as well but may decide to revisit this area (technique). there are many sites, I used this one and it helped me a lot:

ACTION, good luck!
