Hi @JohnFair_425777
Thank you for reaching out to the SMARTY community!
In order to change your payment settings you need to visit the SMARTY app or website, you will see the 'account settings' option and within this you will also see the 'payment method' option. This is where you can update your payment details before the next renewal is due.
Please make sure you change this before your renewal or your account will be suspended if not payment is made.
Please see more information here - Updating your payment method | SMARTY Help Centre
I hope this helps! - Jodie 😊
