Kiara relayed the following from the SOE Senior Customer Service Supervisor:
As most of you know from the messaging in game, our petitioning system is currently under going maintenance. As a direct result of this the Questions section of the Service History tab (Where your petition history is located) has been disabled for maintenance. This means that you can not respond directly back to a GM, nor see your petition though our website as you normally would.
As a temporary work around for this issue you can view your incident and its eventual response by checking the email address tied to your account. You will find an email response detailing your petition and a GMs response to your question. If the issue your petition was about has not been resolved to your satisfaction, please submit a new petition including the old petitions incident number for reference. We apologize for any inconvenience this causes and hope to have the system working normally soon.
You can check your current email address by going to https://account.station.sony.com/ and logging in.
