Good luck with that! I just added a Creative Suite license and I wanted to remove a Photoshop license and... I've been on hold for more than one hour... I wish I could rate this experience somewhere. It'd be 0.
Creative Suite is no longer sold. If you just paid for it that's worrying. Creative Cloud? Anyway, as this is a User to User forum, a request to cancel here will have NO EFFECT. You must contact Adobe.
Warning, scammers may contact you privately pretending to be Adobe staff. Adobe will never send you a private message asking you to email an account that isn't @adobe.com, or use Skype. Adobe never ask you for their password. These scammers want your Adobe info, credit cards, your money and control of your computer, please take care.
