I'm trying to purchase a Photoshop subscription, but I can't complete the payment. During checkout, I receive a message saying that the information I entered is invalid, even though my payment details are correct.

I am Vietnamese.
I have contacted Adobe staff on the payment page at least twice, and they have blamed the bank.
I have changed 4 banks and 6 Visa and MasterCard cards, but none of them changed the 3 lines for entering the card number, end date, and SVV; they all reported "invalid input."
I also tried waiting 48 hours to reapply, but it didn't work.
When I contacted the bank, they said there were no orders from the card even after changing 4 banks.
You know, I want you to not evade responsibility and send meaningless messages.
The problem is, I don't have PayPal, even though I have an account, because Vietnam doesn't support PayPal, so I have to use Visa and MasterCard.
I think you won't receive any rejected orders from Adobe because the order wasn't even completed and sent; it was blocked at the card entry stage. How could Adobe possibly see that? Therefore,
I ask directly, please give me a full explanation of this issue!!
This is a very frustrating problem in the community. Vietnamese dong, both mine and my recent earnings.

I purchased the photography plan, but the payment still won't go through, even though the information I entered is correct.

Please ask for advice on payment problems over on
