thats why i wouldn't show off my recon if i had it (even though i hate recon) but like natu said you should try reporting to xbox live i mean i would go all out to find out who stole my account! are you sure that you didn't forget your password or something? because my friend thought that his account was stolen but then he remembered the right password
My friend had the same problem. Just as long as you have some backup questions on Xbox.com, answer them and change the password, the next time this hacker gets off your account. The password will change and he'll be blocked out. Least thats what my friend did.
I like the shoulders and body plate; the helmet is trashy. Anyways/ OP> Try filing a stolen/hacked account to customer support, they'd be best suited to help.
