" I am sorry for the inconvenience, but upon further investigation, we have strong reason to believe that you are a secondary user on the account. As a result, I am unable to release this account to you at this time. Please understand that these steps are taken to ensure the security of our Players and accounts. I realize that this can be quite frustrating and sincerely apologize for the inconvenience it may cause.
