A transaction can fail for a variety of reasons. Double check and make sure your payment information

I am also facing same problem.

Has your problem been solved ?

Try using another web device that accepts scripts and doesn't have VPN enabled.

First, Be sure that everything matches
https://community.adobe.com/t5/account-payment-plan-discussions/issues-with-adobe-account-when-moving-to-another-country/td-p/13126664
Country https://helpx.adobe.com/x-productkb/policy-pricing/change-country-associated-with-adobe-id.html
Credit card https://helpx.adobe.com/manage-account/using/update-billing-information.html
Currency https://forums.adobe.com/thread/1999694
Store http://www.adobe.com/store_selector/storeselector.html

Second, Nobody here can see your account information
What do you see at https://account.adobe.com/
This space is provided by Adobe, but this is not Adobe support
This is a public forum, you need the link to Adobe support, not other users
Help Center https://helpx.adobe.com/support.html is a good place to start
Be sure to remain signed in with your Adobe ID before accessing the link below
Do be aware that wait times are sometimes long before an agent responds
.
You MUST make sure that your browser does NOT block ads, scripts, or pop-ups
You MUST also allow 'cookies' in your web browser for the link to work
This will NOT work if you are using a VPN
.
This link will go directly to the chat option
https://helpx.adobe.com/contact.html?rghtup=autoOpen
Type "Agent" in the chat box to bypass the chatbot and be connected to a person
-Meaning type in the word Agent in the lower right, without the quote " " marks
or
X (aka Twitter) tweet @AdobeCare
.
Adobe does NOT do support by email, so beware of answering anyone who sends you a private message
-click for more information about scammers https://tinyurl.com/10791730

contact adobe support.  there are 2 ways to contact adobe support; chat and twitter (now x):

chat:
if you have or want to purchase a subscription, use a browser that allows popups and cookies
and click here, https://helpx.adobe.com/contact.html?rghtup=autoOpen
in the chat field (lower right), type AGENT
be patient, it can take quite a while to reach a human.

twitter/x:
tweet @AdobeCare

p.s. if you're contacted by anyone (via email or private message), it's much more likely to be a scammer than an adobe representative.
