To update your payment details, please follow this guide: How do I change my subscription's payment method?
After adding a new card, please ensure you have followed the next step to assign your new payment method to your subscription address(es), as described in the guide.
If you are using PayPal, you will need to manage your card details within your PayPal account as unfortunately, we are unable to update these for you.
You can however add a new payment card directly to your account if you prefer to stop using PayPal, by following the above guide.
If you'd like to add a completely new PayPal account, unfortunately, this can only be done by creating a new subscription and choosing the new PayPal account during the checkout process.
Please ensure your billing address is accurate and matches the address that your payment card is registered to.
If you are still struggling to update your payment details, please contact us for further guidance. Please note, however, our customer service team are unable to take payment details directly from you for security reasons.
