Codashop Error 750 Prevents My PES 2026 MC Purchase

I have been trying to purchase MC for PES 2026 through Codashop, but for approximately 3–7 days, I have received the following message every time I attempt to make a purchase: “Sorry, we were unable to complete your purchase (Error: 750).” As a result, I have been unable to complete the transaction.

I am trying to make the payment with my debit card. I also checked my bank’s mobile app, and there is no charge or pending authorization showing. The money is still available in my account, but I cannot complete the purchase through Codashop. Despite making multiple attempts, the system continues to display the same error.

I request that you investigate the cause of this problem, review my account and the payment system, and resolve the issue so that I can purchase MC for PES 2026. If necessary, I would also appreciate being informed about the cause of the problem and the steps being taken to resolve it.
