Please reply to your renewal confirmation email and ask for a refund. Please notice that your support will be cancelled immediately, and if you need help after your refund is processed, you need to renew support at https://www.propersoft.net/renewsupport
Support renewals are refundable within 14 days from the renewal date.
ProperSoft suggests to cancel the support subscription (look for the link in your renewal confirmation email that ends with "S", open it, click "Cancel subscription and then click "Confirm"). This way you will have the support until your renewal ends.
