deleting cc info from origin

I don't trust EA, os i want to take my CC info off- yet i dont remeber if i saved my info when i bought bf3.

i've done this 

our billing/credit card information are stored in a offline cache on your computer. Here are the steps to clean it out.

Deleting Your Origin Offline Cache:
This is for clearing out saved info like passwords or entitlement info stored on the Origin Client.
1. Exit Origin completely. Right click system tray icon > Exit.
2. Navigate to the OfflineCache file. Here's the path:
Win 7/Vista: C:\ProgramData\Origin\DownloadCache{ your email address }
Win XP: C:\Documents and Settings\All Users\Application data\Electronic Arts\Origin\DownloadCache{ your email address }
3. Delete the OfflineCache file.
4. Reboot your computer. ( I did not do myself)
5. Run Origin and login.

but can't find the downlaod cahe- does that mean i don't have my cc registered with my account?

is there any way to make sure my cc is not on origin?
