If you have placed a pre-order for the PlayStation 4, there are a few steps you can take to get your money back. First, contact your retailer and ask for a refund. If your retailer refuses to process a refund, then you may have to take legal action. Next, try contacting Sony Interactive Entertainment America (SIA) and asking for a refund. If SIA is unable to process a refund, then you may have to take legal action. Finally, if all of these steps fail, you may be able to file a claim with the PlayStation Network support team.
