Hi, @josepuma. You are also free to open support tickets for anything billing related for any team plan type.
Our support team can remove the payment method on file. Before we do this, I see one of the sites on this team still has the paid “Forms level 1” feature. Before we remove the payment method we want to confirm that all billable services are stopped. Would you please change the form level for that site here:
https://app.netlify.com/account/billing/
(Note, that link will only work when logged into the Netlify web app.)
Please reply here (or email support@netlify.com) once the forms level is back to level 0 and our team will remove the payment method and follow-up to let you know when it is done.
