adobe stock subscription cancellation

I don't see how your email address would make any difference.  Either you cancelled or you didn't. Or maybe you had 2 accounts and you cancelled the wrong one??

Let me move this to the Account, Payment, & Plan forum for you, which is the appropriate forum for your question.

The Using the Community 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.

Adobe provides support through the Chat function on the contact page or through a phone call. There is no email support.

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

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.

PHONE: You can also search this page for a regionally appropriate phone number for customer support.

Like you, they are feeling a great deal of stress. A little patience and understanding will go a long way to helping you in your particular situation.
