So this is the response i got from the support team
"My apologies for the confusion, if you were reset in Call of Duty: Modern Warfare 3 there is no way for us to restore your rank. I wish there was more we can do for you but sadly it is not within our power."
What i dont get if its not in there power WTF is the point of them being even there if they cant handle something as small as this, still quite annoys me that no notification was given at all about this happening!!
