Characters unable to be deleted

The same happened to my friend. He created a new character then deleted it at a very early level because he messed up the stats, then created a new character with the same name, all of this during the rollback period. After the rollback, he ended up with two characters of the same name and couldn't delete either of them. For some reason, when he was sent a wedding invite, it went to his first one instead of his second one, which he's now actively playing, but everything else works as he's logged on.
