Cancelling my monthly subscription is impossible.

Hi Anthony,

This is really unfortunate. If you have forgotten the access to your email address, you can always try to recover it. Please do not share any private or confidential info here as this is a public forum.

Please see https://adobe.ly/49IHHYJ for information on how to update the e-mail address associated with an account. 

Let us know if you have any questions.

You're blaming your own faults on others. How can you have a subscription without knowing what email address you used? How did you create it? If you have a subscription, then you can talk to an agent, as you're a paying customer. If you believe you are being charged incorrectly then demand that your bank stops the fraudulent payment, etc.

Anyway, if you have access to the account then you can cancel your subscription easily here:

This is a public forum, not Adobe support.
Users, including the Community Experts, 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: https://helpx.adobe.com/contact.html?rghtup=autoOpen or through:
Facebook: @Adobe
X (formerly Twitter): @AdobeCare - https://twitter.com/AdobeCare

If the chat window fails to open, then use a different device.
Beware of people contacting you via the forums' messaging system pretending to work for Adobe! Only those with an "Adobe Employee" tag under their name are legit. Also, Adobe will never offer to contact you via Skype, or use an email account that's not under the adobe.com domain.

I have paid over £300 pounds for a product I have used once. My bank has been unable to cancel the subscription. This is morally bankrupt for a company to function this way.
