I have another account on Adobe and I need to cancel the plan of this one

Hi ​@GhaliaQili! Here are some resources that guide you with the process:

• Manage your Adobe account profile 
• Cancel your Adobe trial or subscription 

For more info you can refer this article : Account, Plans, and Billing Help or reach out to Adobe Support directly here: https://helpx.adobe.com/contact.html?rghtup=autoOpen as they’d be able to make account related changes.

Hope this helps!
