Oh, that's disturbing! Renderosity SHOULD be involved considering they take 50% of all sales! That means they expect the merchant to bear the soul burden of any disputes. Look... talk to the merchant you purchased the item from. Most merchants are really sweet people. But just keep in mind why they may want to give you an upgrade on the model or a swap for another product instead of a full refund. I wish you the best. Good luck with the merchant... I'm sure he/she will be willing to compromise, even if the storefront is blowing you off.
