Unable to Complete Fortnite Purchase with Papara Black Card – Payment Fails

I've been trying to buy the Fortnite Crew subscription using my Papara Black Card, but every time I attempt the transaction, I receive the error message: "Sorry, your transaction cannot be completed. Please try using a different payment method." I even tried making the purchase with my virtual card, but it also failed. This is extremely frustrating, as I expected to be able to use my Papara card without issues. Fortnite and Papara, please address this problem and help me resolve it so I can successfully complete my purchase.
