Contacted the SE help desk and all of their potential solutions were duds: re-download ARR from the PSN; reboot PS3 in safe mode and Rebuild Database, then reboot again in safe mode and Restore File System.
I logged on with my secondary character whom I almost never use but who was in an ARR location and messaged the GM, asking to have my main character teleported to a non-Heavensward location so that I can at least get something out of this game. None of the categories really fit, so I chose "Harassment" and reported the Playstation Network itself, not another player, as the harasser because it refuses to see that I own this game.
They say they can't add, or pause or freeze, subscription time, nor can they refund it.
PSN redeemed codes cannot be refunded either. (Ah, the glorious digital future!)
BTW, wonderful quote from Jordan at the SE help desk:
Maybe I'll just develop that secondary character on the Japanese server, who only has one class at level 17. Another partial solution might be to find an internet cafe that has this game, log in once, move out of Ishgard, and then go home and play pre-3.0 stuff. Can you log into this game on a public PC if you don't have a PC game license of your own?
This sounds like a real nightmare. :-( Hope you get it sorted.
