Unexpected charging

No.  We can't cancel anything.  Are you certain a family member hasn't ordered After Effects without your knowledge?  If everything you say is true, it sounds like your card may have been compromised. Contact your credit card company immediately and file a fraud report with local law enforcement.

If after you login to the Main Adobe website and then go and look at your account, Manage your Account, and you do not see a plan for After Effects but your credit card shows that you are paying for it then your credit card number has been stolen and used by someone else to subscribe to that plan.

In that case you need to contact your bank or CC company and dispute the charges and get a NEW CC Number.

Log in to your Adobe account Plans page (accounts.adobe.com/plans) to check the plans you are subscribed to.

This is a public forum, not Adobe support. Users, including the ACPs and MVPs, can't provide support for account, subscription, billing, download, or product activation issues. Support for those issues requires an Adobe employee.

If the CSR refers you to the forums, insist on speaking with a supervisor and keep moving up the chain until you get someone who knows what they are talking about.
