So after looking around the web, I found that you can also look at your linden transaction history. If you provide a screenshot and open an online ticket with second life, I think you may have a chance of being refunded, because from what I understand, the merchant did not receive the lindens you paid.
Here is the link for the linden transaction history, if anyone needs it: https://secondlife.com/my/account/transactions.php?lang=en-US
Furthermore, you can submit an online ticket here: https://lindenlab.freshdesk.com/support/tickets/new
