Corendon Airlines Charged Me Twice for a Single Ticket—Requesting Refund

I recently booked a ticket with Corendon Airlines, but during the payment process, I encountered an issue. Although I received a "transaction failed" message for my registered card, I proceeded to pay with another card. Later, I discovered that the amount was also deducted from my registered card, resulting in a double payment for the same ticket.

I am now requesting an urgent refund for the extra charge. As a retiree, I expect Corendon Airlines to handle this matter responsibly and promptly. It is incredibly frustrating to deal with such errors, and I hope to see swift action to resolve this overcharge. Please process my refund immediately.
