I am sure if you contact Activision tomorrow and explain the issue they will be able to resolve it. I have read somewhere else that someone was hacked and they were able to reinstate their previous statistics, it may take a few days to take effect I believe, but don't worry, I am sure they can fix this.
On another note, I made a post about Modern Warfare yesterday, asking if there is many that play it still? As I am thinking of buying it again, and are the servers back online? As I read multiplayer was not playable anymore.
i have same problem... but i dont up level... one day at the end of match my challenges are all over completed and i cannot unlock more challenges and sights... i cannot get sights... i can unlock weapons.. without sights.. this is my problem and i want reset my online account or fix this debug.
support of activision is very primitive... they are supporting only new games. from chile i cannot call for phone.. this call can cost like a ferrari
my ps3 is new.. i dont like piracy, hacks.. i change my pc for ps3 for this motive..
