In most cases, if you're seeing charges around the time you cancelled, it means your account wasn't cancelled before your trial ended or before the next billing period began.
If you're seeing a $1 charge, this is a preauthorization and won't actually clear your account. Please go here for more details.
If you have still have a question, or believe you might have unauthorized or fraudulent charges, please send us a message. We can usually help resolve any issues, and it's much faster than opening up a dispute with your card company. Thank you!
