I'd be suprised too if I still get charged for my canceled subscription. You may still have a recurring payment in the system. Don't worry this can be removed through your Paypal account, simply log in to Paypal, find the recurring payment and click cancel.

If you have done this but are still getting charged, our Customer Support team can help you resolve this concern.
