Hello @kolby12,
Welcome to the Roku Community.
We understand that you wish to change your billing date, but as per advice on streaming subscriptions, billing dates cannot be changed as they are set on the day when you started your subscription.
If you need additional support, for account & billing concerns, it may be more effective to get help from our Billing team. You can contact them here: then choose 'Account, payments & subscription'. They are the best ones to help you out with that matter.
Hope this helps. Please let us know if there is anything else we can assist you with.
Regards,
Nimfa
