Email Regarding
 

The following link was sent to me in an email, while i'm not banned I got a warning for games I haven't actually played. The thing that confuses me is I haven't played Ryze, LeBlanc, or Darius. I don't even own darius either. I feel as though im getting a case sent to me and a warning put on my account that's not even mine?

If you truly believe the attached case to not be yours, I suggest opening a service ticket.

That's what i'm going to do, I mean it's not a huge ordeal given it's just a warning, but I don't want it to come up somehow and get banned for something I didn't do, know what I mean?

Is it possible that someone has created a second account and used your email address for it? And that this second account is the one in trouble? Something to consider
