Payment error for Illustration in Vietnam region

I am encountering the error: 'We couldn't process your payment. Please check your payment details. If the issue persists, try another payment method or contact your bank' when trying to purchase Adobe in the Vietnam market. I have tried multiple payment methods, but none worked. I am wondering if payments from the Vietnam region are currently blocked. I spoke with a support agent, but the prices they quoted for the apps were different from my local region's pricing. Furthermore, I looked for authorized resellers in Vietnam, but they only sell business plans, not individual ones. Please help me find a solution to resolve this issue.
