My origin account is listing achievements and origin points for Dead Space 3 that I haven't earned from back in February. Also I have someone on my friends list that I never added/accepted. It's a bit weird really. I've no reason to believe anything else odd has happened or that my account is compromised. Basically I just want a progress reset for Dead Space 3 and I can remove/block him myself. I'd rather have sorted this by live chat but it's unavailable.
