Do not confirm order delivery, or you won't be able to argue it. Contact your Seller and try to solve the problem directly. These situations are usually a result of a mistake. The Seller will voluntarily replace the item with the ordered one and/or provide the requested service for free. In the case the Seller refuses to deliver the ordered item, you are entitled to request a full refund from arbitration. In the case that the service is only partially different from the one you ordered, the Arbitration manager may order a partial refund depending on the portion of the job done.
