If you wish to change the credit card against your recurring member subscription you can do this by logging into your account and then use this link to head to billing:
https://members.agi.org.uk/membership-account/membership-billing/
If you encounter an issue doing this, you can also access your ‘my account’ and there you will see an option update the billing.
Please feel free to contact our AGI Membership Support team, if you encounter any issues on info@agi.org.uk
