If that does not work, you will need to contact Adobe customer care. There is no need for a PM, as this are public information. Adobe customer care can be contacted by beginning a secure chat session at https://helpx.adobe.com/contact.html?rghtup=autoOpen. Pop-up blockers need to be disabled! If the chat window fails to open, or is non-responsive, use a different device to start the interaction. Support phone numbers may be found here: https://helpx.adobe.com/contact/phone.html. Please note that phone charges may apply.
Additionally, I would like to let you know that you will lose access to any unused licenses if you cancel your plan, so you'd need to use them prior to cancelling.
First of all thanks for reply. I tried all links above but no luck for me. I can not even reach any real person to chat about how to cancel my adobe stock. I followed all step from "Contact Adobe Customer Care" It only ask me to "Choose a plan or product and issue above" and Eventually I end up to here.
Which brings me to my first question. I CAN NOT FIND SWITCH PLAN OR CANCEL PLAN button in my page.
So to make this case easy for us, could you please just cancel my adobe stock membership ?
