Well mine was kind of a similar experience.Had no problems with the actual filling in of the forms, no error messages etc.However when I get on to the selection screen the character I want to restore isn't there.I phone them up and they check my POL ID etc and all the info.There are only 2 IDs to check on so theyask me if I made another char over this ID.I tell them no and I didn't cancel the ID either.They cannot find any record of the char ever existing.They are looking into it and said they will contact Japan to see if they can help as its a mystery.They even used my data to try and find it themselves at the centre.I am wondering if maybe its going to take a day or so for them to show up.I went looking on forums and found a guy who had tested this reactivation theory and it seemed that chars could take up to 3 days to appear.So.....I reactivated 3 old ID's I have not used for ages and deleted them.I went back to the char reactivation service and whilst more old chars from the new IDs showed up the ones I had just deleted didnt.So.........I am going to pray that my char WILL show up over the next few days.
So no, your not the only one whos char data has dissapeared off the face of the earth.Keep me posted on any luck you might have.
