i get an error when i try to cancel my annual plan

Let me move this to the Get Started forum for you, which is the appropriate place for questions about accounts, subscriptions, and billing.

The Community Help forum is for help in using the Adobe Support Community forums, not for help with specific programs. Product questions should be posted in the associated product community.

This is a public forum, not Adobe support. Users, including the ACPs and MVPs, can't provide support for account, subscription, billing, download, or product activation issues. Support for those issues requires an Adobe employee.

Click the following to contact Adobe customer support staff for help:

You must be signed in with your Adobe ID and allow cookies in your web browser for this to work.

This is the link to the US website. If you are not in the US, the site should redirect to the page appropriate to the region associated with your ID.

Click the chat icon at the bottom right of the page to open a chat session. Typing AGENT into the chat window should connect you directly to a CSR rather than the AI.

If the CSR refers you to the forums, insist on speaking with a supervisor and keep moving up the chain until you get someone who knows what they are talking about.

You can also search for Adobe customer support using your favorite search engine. This will normally provide you with a regionally appropriate phone number that you can use.
