Please note that if you downloaded the trial from us (alfasoft.com), we do not ask for credit card details or auto-charge anything. Also, if you buy your license from us, you get free technical support included with your purchase.
If you didn't download the trial from us, you probably downloaded it from Clarivate (endnote.com), and the following applies:
- You entered your credit card details when signing up for the trial.
- You get one email confirming your sign-up and another email 7 days before your 'upgrade date' reminding you that your trial will automatically upgrade to a paid order.
- Both emails include a 'Manage my subscription' button that will bring you to a page that allows you to toggle your trial from an 'Automatic' to a 'Manual' upgrade, update your payment details, or cancel your trial altogether.
If you want to cancel ahead of the notice, and none of the above works, then you should call Clarivate at +44 8003288044 or email them at account.support@clarivate.com.
