https://helpx.adobe.com/contact/phone.html may help

make sure you're following this before giving up on online cancelation, https://helpx.adobe.com/manage-account/using/cancel-subscription.html

if that fails, retry chat:

using a browser that allows popups and cookies, contact adobe support during pst business hours by clicking here, https://helpx.adobe.com/contact.html

click contact us (in the lower right)
in the chat field, type AGENT
be patient, it can take quite a while to reach a human

if that fails, make sure you're using a browser that complies with the above and then google whatever phone number you seek.  but trying to contact by phone is likely to be a (more) frustrating experience.
