If you brought it from eBay you can contact the seller and let them know about the issue. From there you could file a claim with eBay to help resolve the issue. If you didn't use some kind of protected site to do this transaction you're out of luck unless the seller can release the switch.
To save you the time support will not be able to help in this case. If you were the original buyer sale could have helped you here, but since that isn't the case you are left with very few options.
