First of all: we are sorry to see you go! We understand there can be many reasons to end your EasyVFR subscription, but we would appreciate to hear about them through email@example.com.
If you used Paypal to pay for your subscription before, you need to log in at Paypal and stop the automatically renewing license.
By the time your license for EasyVFR expires you will get a few emails from our automated back office system, reminding you of the pending expiration. But if you ignore those then your subscription will terminate by itself. Quite easy! ;-)
If you paid by bank transfer your licence will not renew automatically and there is nothing you need to do.
