If you live in the USA, Email their support and declare that you've canceled your account with them and refuse to pay anything further. Then contact your credit card company and initiate a charge back. If your CC company wants proof, send them a copy of the email you sent. Every chargeback a company gets costs them money, on top of the money they aren't getting from you. If a company gets a high enough charge back rate, their credit card processing vendor will revoke their services. Fraud/Chargebacks are a MAJOR issue for any company accepting credit cards. If you've made it clear you wish to cancel and are in no other way violating a contract (ex: You signed up for a 1 year subscription billed monthly with Adobe Cloud, ya gotta pay them for the year), then you are free and clear.
