You may unenroll your accounts from automatic payments by navigating to the Billing Summary from the insured's account page. Just click "update" next to the payment information, then "unenroll" on the next screen, and finally "save changes" to confirm.
Be aware that if payment has already been charged or drafted from an account, unenrolling from autopay will not stop payment from being made. You or the insured will need to contact the bank that payment is being remitted from to stop the payment.
Please note you may need to refresh your page to see the changes reflected.
