Error 99 When Buying From Dyson Turkey

I attempted to place an online order on Dyson Turkey’s website as part of a gift opportunity campaign, but my payment could not be completed despite multiple correct attempts. Each time I tried to pay by 3D Secure, my bank sent me the OTP code and I entered it correctly, and I even received a “payment approved” message after entering the OTP. However, the Dyson website itself then displayed a “Payment Failed” message with error code 99 and a transaction ID indicating that the payment was unsuccessful. On 21 August, I tried to complete this payment at least five times. When I spoke to my bank, they informed me that no payment attempt had even been initiated by Dyson’s side, despite my repeated tries, the OTP messages and the payment approved notification. In addition, Dyson did not respond to me about this issue, which has made the situation even more frustrating while I am trying to benefit from a gift opportunity. I request that Dyson urgently investigate these failed payment attempts, ensure that my order is processed correctly, and complete the payment securely without further errors. I also expect a clear and timely explanation and communication about what went wrong and confirmation that I can successfully finalize my purchase.
