If exceptional circumstances mean you need to request that your Membership ends before its normal renewal or anniversary date, use the immediate cancellation process.
From the cancellation page, follow the link underneath the renewal options to:
Immediate Membership Cancellation Request
You’ll be asked for more information about your circumstances and will need to confirm that you understand what ending your CMA Membership means.
Submitting this form is a request for review and does not automatically cancel your Membership. The Membership team will contact you once your request has been considered.
