I have a payment error

I want to purchase the Adobe Firefly Standard and Adobe Creative Cloud Student plan. After entering my card details in the payment section, I click on the "Accept" button, but the payment is not processed. It shows a warning that the payment has not been completed and asks me to contact my bank or try another card. I’ve tried three different cards, but none of them are working. The website address starts with https://commerce.adobe.com/store/payment. Can you help me? 

Note: My cards are enabled for international online shopping,no restrictions, and they have sufficient funds available.

The actions I took: I corrected the billing address, I tried different credit cards and bank cards, I tried with different accounts, I tried with different browsers and devices, I tried by resetting my browser data, I contacted Adobe support, I contacted the customer representatives of the banks many times.

Error:The transaction may fail for a variety of reasons. Double-check your payment information and make sure you entered it correctly. If this issue persists, you may need to use a different payment method or contact your bank.
