Hey thanks for the feedback guys, what my MP said was that he thought that it was completely unfair and he would initiate inquiries. So the Conservatives have got my vote in future.
I'll see what my MP can do and then take it further and further, I've got a couple of years to get this sorted anyway now because I have started 6th form. Being refused from the Army has been somewhat of a blessing as well as very upsetting at the same time, if I had been accepted then and not (hopefully) after my A Levels I would probably �16,000 worse off a year because I wouldn't be an officer.
I will look into the NAS as you suggested Karen, and again, thanks for all the information and support people! =)
