As I had mentioned in a post last year that is quite ironic, even though CO (and others) are very quick to say we will close your account with 3 years inactivity, when I requested that my CO account be closed and my personal information purged from their database the answer given was that we will no longer contact you about your account but we do not have the ability to erase you from our database.
BTW: I still receive monthly e-statements and promo offers from CO.
