Unfortunately, the mog cap and cait sith minion were only available as a benefit for those that pre-ordered the game. Were you not able to input the code before the 29th? I think the only way that you are going to get this sorted out is if you contact SE directly...

EDIT: Just re-reading through your post, if you were affected with that error, then surely SE should be able to apply those items to your account? Hope you get it sorted out soon
