OMG the steelbooks looks really worse....but anyway I don't like it that someone from this forum did you a favour and that he he is now pilloried in a public thread. I think this is something you have to discuss with the seller privately. Maybe he will give you a half refund and after his claim was successful the rest? :/ But I don't think that it was the sellers fault so in some way I can't approve of with this thread and I already started to think of not providing anymore help because you're always the bad guy as the seller.
This is just my opinion so don't take this personal.
