Techs will restore a deleted character once and only once. You need to know the name, server, basic level information, race, jobs, etc in order to further help their search.
The process can take up to one real life week, or it can take as little as two hours, depending on how much the techs feel like busting your balls at the time (mine took five days).
If you call the Play Online tech service number found on their website, or in your FFXI booklets that you received with the game, it'll give you touch-tone options, etc.. then you'll be put on the line with a live customer service representitive.. and I use the term loosely... and you'll be directed on what to do.
