Hello @Thuy33697112vjbd, Look at the following link for information on how to cancel your subscription. https://helpx.adobe.com/manage-account/using/cancel-subscription.html If the information does not help, then you need to contact support. To contact support follow the instructions given below 1. Go to https://helpx.adobe.com/contact.html?rghtup=autoOpen 2. Wait a bit on the page that opens up, it should automatically open a chat popup. If that does not happen then look for a call out/chat icon at the bottom right, click over it and the chat popup should open 3. In order to talk to a human type "AGENT" in the chat box 4. If you are not able to get to the chat window, then disable your adblockers, firewall, enable cookies/scripts on your browser. If it still fails then change your browser/machine/network.
