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.
Sincere_Flower, which subscription did you attempt to cancel? I see an active subscription under the account you used to post to this public discussion forum.
Please see https://adobe.ly/4gOLB4A for information on how to cancel your active plan. For additional information on the applicable charges for an annual membership, see https://adobe.ly/4gTDi7p.
You may need to use a different device or web browser if you cannot see or manage your active plan. ^JW
